Video Game / Sonic Robo Blast 2 Kart

Go To
Sonic Robo Blast 2 was a Sonic fan game built using the 3D Doom Legacy engine and is regarded as one of the finer Sonic fan games to have ever hit an official release... And then someone wondered what would happen if you added karts to the equation.

The result is the aptly titled Sonic Robo Blast 2 Kart which is Exactly What It Says on the Tin: A Doom Engine powered kart racer starring Sonic and his friends racing and battling it out on 100 maps. Or at least, only Sonic and his friends and only 100 maps to start with, as the game was designed with mods in mind and even starts every player with some bonus characters to show off what can be done. The game allows for up to 4 players to play offline or go online for up to 16 player online matches, though it currently lacks any form of AI racers. It was officially released on November 16th 2018. Needs Wiki magic.


This game contains examples of the following tropes:

  • Always Night: Roughly 20 race tracks and at least 4 battle courses take place at night.
  • Anti-Frustration Features:
    • This game's version of the dreaded Blue Shell, the Self-Propelled Bomb, doesn't necessarily mean certain doom for the racer targeted by it — skilled players can easily outrun it, so much so that they can even complete the race without being hit by it.
    • Players who drag items behind them are slowed down a bit, meaning that you they cant just hold onto them to use as a cover against incoming attacks without risking their speed. Items are also dragged behind/orbit the player by default, meaning they can’t just not place the item out to circumvent the speed decrease. (This swings both ways though, as the speed decrease is not significant to the point that players will simply want to just place their items the second they get them.)

    • Although it's technically not an in-game feature, those who want to play the Map Hell levels but are struggling to earn the necessary amount of Record Attack medals (110 out of 115) can download a mod created by one of the game's developers to freely access all of the cup's maps, including those which have been removed in certain patches.
  • Amazing Technicolor Battle Field: MKSC Rainbow Road is an available course. SMK Rainbow Road can also be found in Map Hell.
  • Art Shift: As the Bonus Characters pack contains characters made by various authors, some vary slightly in their art style. Beat, in an attempt to mimic his home series' style, has sharper outlines and shading.
  • Breakout Mook Character:
    • In Super SRB2 Kart Z, Robo-Hood, one of Sonic Robo Blast 2's Badniks, could be added via the "misc characters" file that came with the game. Similarly, there was Crawla Honcho, a Crawla with a honcho getup that spoke in The Soldier's voice.
    • This role would eventually go to Motobug in SRB2Kart proper while the aforementioned Robo-Hood and Crawla Honcho were scrapped from the playable roster.
  • Brutal Bonus Level: The aptly-named "Map Hell" cup, which you can rarely come across online if someone votes the "random track" option, and is not available for singleplayer until you collect 110 of the 115 medals. Not all of the maps in the cup are difficult, but many stand out:
    • Septic Quarry's layout mostly lacks guardrails and typically has at least one side of the track surrounded by pits, reminiscent of Colorado from Mickey's Speedway USA. As of the 1.0.2 update, it has been Dummied Out of the official track rotation.
    • CK Cloud Tops 1 completely lacks guardrails and features some tight turns, making it all too easy for an inexperienced player to fall off the course.
    • CK Dungeon Maze works less like a track and more like... well, a dungeon; all kinds of obstacles and traps appear to potentially ruin the racers' day.
    • CK Death Town has a very unforgiving layout, mostly featuring turns that can have you careening into a pit if you mess up. One particular turn near the end happens to be much narrower than usual, making drifting around it very risky in comparison to just slowing down and taking it cautiously. Like Septic Quarry, it has been removed from rotation as of the 1.0.2 update.
    • Silence from F-Zero makes an appearance here. While it doesn't have any hazards itself, the map only has 90-degree turns and barely has breathing room for driving, making a race between several players a claustrophobic nightmare.
    • The infamous five-lap smaller-scaled Rainbow Road from Super Mario Kart also shows up here. Expect players to constantly fall off the track, especially if items are cleverly (or poorly, in the case of speed-up items) used.
    • Crystal Abyss is one of the game's longest tracks, even though it only lasts for two laps, and is peppered with tricky turns to boot. In addition, the level is arguably the most visually-detailed in the entire game, thus it can (and likely will) cripple performance with weaker computers. Crystal Abyss was actually the very first track to end up in Map Hell; the aforementioned issues meant that having it only appear occasionally worked best.
  • Build Like an Egyptian: Ancient Tomb Zone is a long track taking place in a pyramid.
  • The Cameo: In addition to being one of the bonus characters, NiGHTS appears on a poster in the Dark Race and Twinkle Cart levels.
  • Casino Park: Casino Resort Zone is a casino-themed race track, featuring slot machines and giant poker chips along the edges of the main path, and even a giant roulette wheel as part of the track itself.
  • Character Customization: Players can select from a wide array of colors/pallettes to help identify each other online. Very useful as by default there are only 5 characters.
  • Competitive Balance: The character select screen outlines the two mutually exclusive stat pairs for players. Top speed vs acceleration and handling vs weight. These points are stressed with the bonus characters Gamma, Chao, Omega, and Flicky (or Aigis before 1.0.2) who are each put in a different corner of the grid.
  • Demoted to Extra: Robo-Hood went from a playable racer in Super SRB2 Kart Z to a background prop in Eggman's Nightclub Zone.
  • Developers' Foresight:
    • In Desert Palace, there's a red button which temporarily removes the shortcut over a certain pit. When pressed, however, the button cannot reset itself until the player who activated it completes a lap; this stops potential Griefers from just camping at the button and using it to mess with other players.
    • In multiplayer, a Map Hell level is guaranteed if everyone chooses the "random" option in the voting menu. In the singleplayer Free Play mode, where the same vote window appears, choosing the aforementioned option instead loads a random regular level, thus you are forced to unlock the Map Hell cup for singleplayer the hard way. You can, however, play multiplayer matches privately, finish a race, and trigger a Map Hell selection to race on them freely.
    • The main way to get the various unlockable tracks and modes in game is through Record Attack, but for those who aren't skilled enough to unlock everything can instead unlock them simply by playing enough matches. Even Free Play counts.
  • Difficult, but Awesome: Metal Sonic is as fast as Sonic but traded handling for weight, making him harder to control but much more powerful with drift boosts. Omega takes this even further by maxing out on both weight and speed.
  • Floating Continent: Silvercloud Island Zone, a floating island track that even has a small town.
  • Fragile Speedster: Sonic is naturally one of the fastest characters, but he's also pretty light. Bonus characters Blaze, NiGHTS, and Flicky (Aigis before 1.0.2) have stat cominations close to Sonic's, with Flicky taking this the furthest by being both one of the two fastest characters and one of the four lightest.
  • Game Mod: SRB2Kart is an open-source mod of an open-source mod of Doom Legacy. It also supports the option to add new characters, levels and even modified game modes, and includes a few bonus characters as an example (though it is impossible to unload mods without restarting the game).
  • Glacier Waif:
    • While not that heavy, Miku is still rated 6 on the weight scale, making her the heaviest female racer in the base game, only slightly lighter than the likes of Vector.
    • Mighty also manages to be as heavy as Eggman despite being the same size as Sonic and lacking Metal Sonic's, well, metal excuse.
  • Glass Cannon: Characters with overall high top speeds (either an eight or a nine in said stat) are some of the quickest racers in the game in the right hands, but their acceleration leaves a lot to be desired- meaning one mistake or an incoming attack aimed right at them will send them much further back before they can catch up.
  • Go-Karting with Bowser: Sonic and friends can go kart-racing with the villainous Dr. Eggman and Metal Sonic.
  • Green Hill Zone: As one would expect, the Trope Namer is the first level, though it takes its style and theme after Green Hills Zone from the 8-bit version of Sonic the Hedgehog 2.
  • The Grim Reaper: Appears as a hazard on the Mementos arena.
  • Guest Fighter:
    • Several bonus characters come from other Sega properties. Wonder Boy (in Dragon form) and Aigis have been present since the initial release, while 1.0.2 added AiAi, Arle, and Hatsune Miku (whose Project DIVA series is made by Sega), and 1.0.4 added Beat, NiGHTS, Kiryu, and Ulala.
    • In SRB2Kart's predecessor Super SRB2 Kart Z, Waluigi in his Brawl in the Family design was present in the bonus add-on file (misc.kart) bundled with the game, but to limit the influence of Mario content in SRB2Kart and since the skin was never updated to match the standards of the other characters for SRB2Kart, he was ultimately dropped.
  • Half-Dressed Cartoon Animal: Bonus character Aiai stands out as being the only one of these.
  • Jack-of-All-Stats: Knuckles is placed perfectly in the middle in both speed and weight. To a lesser degree, Aigis, Beat, and Espio qualify as well, with each having a stat combination only slightly different from that of Knuckles.
  • Lethal Joke Character: Despite being just one of the many tiny animals Sonic rescues on a daily basis, Flicky can be a formidable opponent in the right hands, being maxed out in both Handling and Speed. Before 1.0.2, these stats belonged to Aigis (who is now closer to a Jack-of-All-Stats).
  • Lethal Lava Land: Volcanic Valley Zone, the final track in the Emerald Cup, and Boiling Bedrock Zone, the second track in the Egg Cup.
  • Level in Reverse: The unlockable Encore Mode, which mirrors the track and also gives it a palette swap, obtained from getting 70 medals or playing 300 matches.
  • Lightning Bruiser: Metal Sonic is as fast as he is heavy, letting him knock other racers around while also maintaining high speed, albeit at the cost of Acceleration and Handling. Bonus characters Vector and Omega also qualify, with Omega in particular having the highest possible top speed and weight.
  • The Lost Woods: Midnight Meadow Zone, a nighttime track taking place in a forest with falling apples as obstacles.
  • Made of Explodium:
    • Last place simply explodes once everyone else crosses the finish line, F-Zero style. Also, anyone who doesn't cross the finish line before time runs out after over half of the racers had finished the race will explode as well.
    • Hitting the Toads in Arid Sands sends them flying a short distance before exploding spectacularly.
  • Marathon Level: Crystal Abyss Zone, a two-lap track that takes about three minutes on average to complete. Its length is one of many reasons why it's the first track in Map Hell.
  • Mighty Glacier: Eggman has one of the highest weights in the game (tied with Metal) and has the highest drift spark charge rate, but has very low top speed. Among the bonus characters, there's Chaos Zero, who's slightly faster than Eggman but also slightly heavier, and Gamma, who takes this to the extreme by having the highest weight, but also the lowest top speed. Played With due to the fact that a low top speed also means a high acceleration and the ability to charge boosts faster while drifting, meaning they can reach said speeds faster and recover better than most other racers.
  • Mythology Gag: Several nods to both the Sonic franchise in general and Sonic Robo Blast 2 specifically are scattered throughout the game:
    • Most items available in Item Boxes are available in monitors from the official Sonic games as well. Aside from series mainstays such as Invincibility and Power Sneakers, several come from more obscure sources:
    • With the exception of the SMK Cup, the cups are named after various items and other objects from the series, with three of the cups (Water, Lightning, and Fire) being named after the shields from Sonic 3 and Knuckles.
    • The first track of the Invincible Cup is based on Desert Palace Zone, also from the Competition Mode of Sonic 3 and Knuckles.
    • Numerous tracks are based on Sonic Adventure or Sonic Adventure 2. Notably, almost all Sonic Adventure 1 levels are named after the song that plays in the area they're inspired by, as opposed to the name of the level itself.
      • Dark Race, the second track in the Ring Cup, is inspired by the Chao Races from Sonic Adventure 2.
      • There are four levels based on Twinkle Park: two of them (Twinkle Cart and Pleasure Castle) appear as the final two tracks of the Water Cup, while the other two (Fakery Way and Bumper Carts) appear as battle courses.
      • Red Barrage Area, the penultimate track of the Invincible Cup, is based on E-102 Gamma's version of Hot Shelter.
      • Egg Quarters is the third track of the Egg Cup.
    • Among the tracks in the Swap Cup are Balloon Panic from Sonic Drift 2 (albeit with the random balloon effects replaced by simply launching the racer upward) and a repurposed Special Stage 3 from Sonic Mania.
    • One race track in Map Hell is based on Arid Sands.
    • Among the many Battle Mode maps are Marble Zone, Death Egg's Eye, Power Plant, Colosseum, Tails' Lab, and the first special stage from Sonic CD, with the latter 3 courses lifting their layouts straight from their original games.
    • Badniks from Sonic Robo Blast 2 appear in the background of several tracks. One of the selectable palettes, "Robo-Hood", is even named after one.
    • Frozen Night from Robo Blast 2 appears as a Map Hell race track, and Meadow Match appears as a Map Hell battle course.
  • No Fair Cheating: Certain mods aren't allowed in Record Attack, as the staff ghosts were all designed with the default cast and systems in mind. As of 1.0.3, the only exceptions are custom characters who don't use Lua and custom tracks that don't replace existing tracks.
  • Nostalgia Level: Map Hell includes several levels from earlier incarnations of SRB2Kart that were removed from the main map rotation:
    • The Peach's Castle race and battle courses date all the way back to when the mod was just a mode for the SRB2 Riders mod.
    • Black Bliss and Chemical Facility both originated in the Super SRB2 Kart Z version of the game.
    • "Classic" versions of Volcanic Valley, Diamond Square, and Blue Mountain based on the aforementioned Kart Z versions are also present.
  • Palmtree Panic: Sapphire Coast Zone and Aurora Atoll Zone both take place in tropical environments, with Sapphire Coast taking place during the day and Aurora Atoll taking place at sunset.
  • Shifting Sand Land: The tracks Sand Valley Zone, Desert Palace Zone, Barren Badlands Zone, and Egg Quarters all take place in deserts.
  • Shout-Out:
    • Misty Maze Zone from Sonic the Hedgehog Megamix appears as a track, even using its remix of "Industrial District" from Columns III instead of the slower-paced original composition.
    • The final track of the Invincible Cup is the Midnight Channel.
    • One cup (aptly named the SMK Cup) exclusively features tracks from Super Mario Kart. The game's four Battle Courses are available in Battle Mode as well.
    • A few other levels from the Mario Kart franchise can also be found elsewhere in the game, including the Mario Kart: Super Circuit version of Rainbow Road and two battle maps from Mario Kart 64.
    • On top of the several Mario Kart racing tracks, Lava Bubbles appear as obstacles in Volcanic Valley Zone, and in the background of Boiling Bedrock Zone.
    • Peach's Castle is an original track found in Map Hell. Toads with sprites ripped from Super Mario All-Stars also appear in Arid Sands, using Toad's Mario Kart 64 scream when they're run over.
    • Ganbare Dochu 2 from Konami Krazy Racers appears as the first track in the Chao Cup.
    • Map Hell includes a few more race tracks from other games, namely Retro Maze from Pac-Man World Rally, Silence from F-Zero, and Rainbow Road from the original Super Mario Kart.
    • Among the battle courses are Armored Armadillo, Trigger Happy Havoc, and Mementos.
    • One Map Hell battle arena level features Sweet Bro and Hella Jeff as wall textures.
    • The "Plague" color available for use on characters is styled directly after Plauge Knight's colors.
    • If you happen to throw a banana at another racer before it lands, you'll hear a ping sound effect.
  • Skill Gate Character:
    • Chao is very beginner friendly and will have an easy time staying on track. However, he is extremely slow and light, limiting his potential. Dark Chao and Tails are one step up from Chao, with Dark Chao being 1 point heavier and Tails having a point greater in both speed and weight.
    • Faster lightweights such as Cream, NiGHTS, Sonic, Amy, and Flicky are also beginner-friendly as they can take turns relatively easy without relying on drifting while also having average to great top speeds. Their only downsides are their poor acceleration combined with the aforementioned lack of weight.
  • Slippy-Slidey Ice World: Race tracks Sub-Zero Peak Zone, Blue Mountain Zone, and SMK Vanilla Lake 2 take place in icy areas with slippery terrain, as does SMK Battle Course 3. In Map Hell, there's also SRB2 Frozen Night and Blue Mountain Classic.
  • Theme Naming:
    • As a Sonic fan game, many of the tracks and arenas end in "Zone", though some exceptions apply.
    • Most of the Cups are named after item box items, with the Water, Lightning, and Fire Cups being named after the shield types from Sonic 3 and Knuckles. The exceptions are the Emerald Cup (not counting its appearance in Sonic the Hedgehog: Triple Trouble, though it is still an iconic Sonic item), the Chao Cup (named after an iconic Sonic species instead), and the SMK Cup (named after the game its tracks are based on, Super Mario Kart).
  • Toy Time: Megablock Castle Zone is constructed from colorful blocks, and features jack-in-the-boxes as obstacles.
  • Videogame Cruelty Potential:
    • You can run into Toads standing in the middle of the track in Arid Sands, causing them to get launched and self-destruct as a result. They provide no penalty for doing so and running them over has no impact on the overall race, but the explosion can spin out racers that drive into it.
    • A more intentionally implemented example is with the battle mode. After running out of Bumpers, you turn into a Self-Propelled Bomb (styled after the Bomb Kart from Mario Kart 64) and can drive your kart into other racers still in the game to destroy one of their bumpers. Destroying a certain amount (or simply striking the player marked as "Wanted" will award you with an extra one of your own and put you back in the game.
  • Weak, but Skilled: Tails is the slowest and lightest of the default characters, but his high acceleration allows him to quickly recover from spinning out, and his excellent handling makes it easy to zip around corners while chaining boosts. Bonus characters that also fit the role include Chao, who takes Tails's stats to their extreme, Dark Chao, who is just as light as Tails but still slower, and Motobug, Ray (Rouge in 1.0.2), and Ulala, who are similarly slow but are heavier.
