is a horizontally scrolling shoot 'em up arcade game released in arcades by Konami
in 1988. Thunder Cross used a "layered scrolling" background, a new 2D graphics technique at the time. A sequel, Thunder Cross II
was released in 1991.
Both Thunder Cross
and Thunder Cross II
take place in the same universe as the Gradius
series. The planet Haniamu IV is under attack from a relentless, unknown military force known only as Black Inpulse. Humanity sends the Blue Thunder M-45 and its earlier make the Red Thunder M-24 to take care of them.
Not to be confused with the Thunder Force
shooter series. And definitely
not to be confused with the alternative name for the swastika
Thunder Cross and its sequel provides the following examples:
- Attack Drone: The Options. They stay at the sides of your ship, although you can control the distance between options (in the Japanese/European version of 1, and in II)
- Attack Its Weak Point: Most of the bosses have a crystalline core which you must damage in order to defeat them.
- Battleship Raid: Stage 4 of the first game, and Stage 5 of II.
- Continuing Is Painful: And how. You lose ALL your powerups when you die! It does reset the Dynamic Difficulty, though.
- Corridor Cubbyhole Run: Stage 6 of II has your character move through an asteroid field◊ while the boss fires a Wave Motion Gun from offscreen. In order to avoid the laser easily, you have to hide behind the asteroids that block it.
- Difficulty By Region: The US version of Thunder Cross gave your character Smart Bombs in exchange for the special weapons and the ability to control your options.
- Dynamic Difficulty: Get enough powerups and the annoying turret enemies will exhibit More Dakka, in a fashion similar to Gradius.
- Expy: Some of the bosses in the series are similar to those in Gradius.
- There's also the "wave" of popcorn mooks that drop a Power-Up when all of them are destroyed.
- Gratuitous English: The second game has boss names like "Brookrans, Works", "Laze, Zoguylum", and "Sproutes, Layber".
- Kill It with Fire: The flame weapon from both games. In 1, it was a continuous medium-range stream of flame, in II, your Options shot out phoenixes that pierced enemies.
- Humongous Mecha: Most of the bosses that aren't ships.
- Mini-Boss: Each level usually has one in the middle.
- Mutually Exclusive Powerups: The primary weapons you could use, as well as the "special" weapons (Napalm, Flame, Laser).
- One-Hit-Point Wonder: Your character, like most games in the genre.
- Palette Swap: Player 1 (Blue Thunder) and Player 2 (Red Thunder).
- Point Of No Continues: The final level.
- Reactor Boss: "Brookrans, Works" from II is the core of a large battleship.
- Recurring Boss Template: Eggeroid, which appears as the first boss in both games. In the first game, you could attack its weak point directly, in the second, you had to attack its tail first.
- Reflecting Laser: The Final Boss of II.
- Reptiles Are Abhorrent: In II, the Black Inpulse have two repilian bosses (Ragamuffin the robotic naga and Dinosaur Junior the robot chameleon).
- Shared Universe: Thunder Cross takes place in the same universe as Gradius.
- Snake People: Ragamuffin from II is a robotic Naga with a shield, rocket launcher, and a stinger tail.
- Spell My Name with an S: The villains are called the Black Inpulse, not the Black Impulse.
- Sphere of Destruction: The Napalm Weapon makes your options shoot out a bomb that explodes into these.
- Steam Vent Obstacle: Thunder Cross II has them in the fourth level. Unlike most of the examples on the trope page, you can destroy them.
- Too Awesome to Use: Subverted with the special weapons. Although they do have limited ammo, hit a large area of the screen, and hurt A LOT, you can easily find more ammo once you run out. Furthermore, they replace the primary weapon of your options, and the only way to revert them back was to run out of ammo.
- Wave Motion Gun: The Laser weapon from both games allows all your four options to fire out one!
