Released in 2015, Super Robot Wars X-Ω was a smartphone mobile game for the Android and iOS platforms in the Super Robot Wars franchise, developed by Sega, that mixed Tower Defense with Real-Time Strategy elements, similar to Chain Chronicle. Unlike the traditional Turn-Based Strategy installments, X-Ω relied on a gacha nature of play, thus allowing its roster to reach into the hundreds of individual series listed, even reaching different genres other than Humongous Mecha from different media. This marks X-Ω at being the most crowded title in Super Robot Wars history (With a whopping total of 192 series being featured!), alongside having the largest number of new debuts (88!).
Ironically, the X-Ω approach of using series beyond simply Mecha would affect future titles, such as Super Robot Wars V, Super Robot Wars X, Super Robot Wars T and Super Robot Wars DD, where the requirements of which series can be included are significantly lowered, with loads of Unexpected Characters popping up. From Super Sentai to Mega Man and even Godzilla, the King of the Monsters himself making an appearance.
The game ended service on March 30, 2021. This was accompanied by the announcement of an offline version that will let players download and view some of their data from the main game prior to its closure.
Series included in X-Omega are (debuting series are rendered in bold):

Super Robot Wars X-Omega provides the following tropes:
- Adaptation Expansion: The game's representation of Gravion gave the unit a special move that debuted in the Pachislot version of the series and was never used in the Super Robot Wars Z saga: Choujuu Dangaiken.
- Art Shift: The Mega Man characters don't use 3D sprites like the rest of the characters in the game — they use the classic 8-bit graphics from the old NES series (or Mega Man 10 in the case of Bass).
- Ascended Extra: Unlike the official games that featured Cross Ange, Kaname & Naga and their respective mechas (Soryugo and Hekiryugo) are solo units obtainable on their own instead of being Assist Characters for Salamandinay.
- Canon Welding: For Getter Robo, this game uses the classic anime version for both the original and G, yet the characters are designed much more closly to Go Nagai's style. Similarly for Getter Robo Go, the characters and their designs are used straight from the manga, yet the anime version of the titular mech is used.
- Combination Attack: Many combination attacks from the mainline SRW make appearance here, such as Twin Mazin Emperor Strike (by Mazinkaiser and Mazin Emperor G). However, there are new combination attacks never seen before in other SRW games, for example, Rondo of Angel and Dragon, a combo attack using Vilkiss and Enryugo.
- Creator Cameo: In one of the backgrounds you can see a building with a Sega logo. SEGA are the developers of this game.
- Fake Shemp: Yuko Mizutani's lines as Excellen Browning are reused from the previous games.
- Fanservice: Some characters fight wearing nothing but swimsuits in this game.
- Guest Fighter: One-Time event series in general were this, having no contribution to the main plot and usually only being featured as a special case or in celebration to whatever said series was going through at the time. A good number of them were also Unorthodox Series, meaning there were a bunch of works that didn’t exactly qualify as Humongous Mecha, moreso than any other Super Robot Wars game before or since. These are only a couple of examples;
- A lot of the franchises Original Generation made its way into the Gacha at some point or another, but the most notable examples are Granteed, Touya, Katia, Festenia & Melua and MoiMoi! The latter is the Series Mascot for a Net Radio Show associated with the franchise who was added
in celebration of its 500th episode, while the former were only included to advertise the then-recently released Moon Dwellers. - Godzilla, the King Of Monsters himself, was also added in alongside the Kiryu version of Mechagodzilla.
- Mega Man got put in alongside Proto Man, Bass, and the Mega Man 2 Robot Masters...and they’re all 8-bit sprites amongst 3D models.
- In celebration of the 30th Anniversary of SD Gundam, the game brought five characters from the sub-franchise into its Gacha, most notably Musha Gundam, Superior Dragon, and Command Gundam.
- A lot of the franchises Original Generation made its way into the Gacha at some point or another, but the most notable examples are Granteed, Touya, Katia, Festenia & Melua and MoiMoi! The latter is the Series Mascot for a Net Radio Show associated with the franchise who was added
- Heel–Face Turn:
- Due to the gacha nature of the game, sometimes a normally unrecruitable villain can be pulled into your roster. You want to have Shagia Frost team up with Garrod Ran? Lordgenome fighting alongside Simon and Nia? Or you want to give Embryo the harem he so wanted to make (minus the unfortunate implications he usually brings)? Sure you can. Or you want a villain with a sense of honor at times? Don't worry, Great General of Darkness (ZERO version) got you covered.
- And they can even make a story based on this trope. Such is what happened to Nena Trinity (the girl who shot an innocent wedding For the Evulz). Synopsis
- Mythology Gag: The Cut-In Portrait for the Omega-Cross variant
of Grand Chariots Miracle Magical Shining Tornado Punch is similar to the Cut-In Portrait for the Omega-Cross variant of Gurren Laganns Giga Drill Break (With Constanze & Akko taking the places of Simon & Kamina, respectively). This is due to the fact that Miracle Magical Shining Tornado Punch is a direct Shout-Out to Giga Drill Break. - Non-Indicative Name: Amongst the new Combination Attack featured in the game is 'Axis Attack', done by Char Aznable and Haman Karn. Unfortunately, it's just a normal 'both related characters attack together in a combo', this is not about dropping the Axis colony right onto the enemy.
- Serial Escalation: We've seen Master Asia featured as a ground unit taking on giant robots on his own feet. Ground unit Master Asia is back in this game, and by this time, the size and power of the robots have far surpassed those that appeared in his time, especially with those from Tengen Toppa Gurren Lagann. Would you like to see Master Asia kicking the universe-sized robots or abominations on his own foot in that series, with just his flesh (and cloth)? Sure thing.
- Tactical Rock–Paper–Scissors: Assigns units with different attributes based on their strengths and weaknesses, where Attackers>Defenders>Shooters>Attackers. In a later update, introduces Blaster and Fighter, which deal extra damage to each other, if not the three previously established attributes.
