Color Fight Windows, X360 game

In Color Fight, players have two main abilities: they can fire with the right trigger, and they can paint the playfield various colors with the left trigger. They start with just blue. Blue is used as a barrier, to block players and fire. Players can chip away blue, incrementally, by firing at it. After that, shortly into the game, players can acquire one of the other two primary colors: red or green.

Red can be used offensively. Unlike blue, players are able to pass through red, but doing so causes them to take damage. Red can't be destroyed unless it's mixed with blue to create magenta. Magenta has the opposite properties of red; It heals players and is able to be destroyed. So with red in play, there are more ways to take damage but theres also a way to heal. Movement also becomes more strategic as there are now additional ways for players to trap and screen each other.

The last of the three primary colors, green, is the most eccentric. It simply curves the path of objects that pass through it. This allows players to curve their fire around cover, and makes lining up shots much less trivial. Green curves clockwise -- yellow on the other hand curves counter clockwise; so with enough planning, players can make objects travel along any arbitrarily complicated path they like. Green allows for a lot of other emergent gameplay tactics that I won't go into. I'm hoping people will find satisfaction in discovering them themselves.

The last color I'll mention is white. If all three colors manage to combine and create white, they become very unstable and explode when fired upon. This can be used to set up chain reactions, typically turning the screen into a flashing, strobing, mess of particles and debris.
