Chromacide is a puzzle shooter game, where the puzzles work kinda like rock, paper, scissors

whereas (red > yellow > blue > red). You, and the enemies change colours from going through gates, or from collecting pickups. The two enemies in the game are the Turrets, and the Wardens. The Turrets look at you and shoot in intervals, whereas the Wardens moves along a path, and if you enter their field they move, and shoot at you. The weapon, and GUI change to match your current colour. The weapon shoots a ray-cast to find the targets, and created a line to create a laser pointer type of effect. There are some parameters set up for enemy/player interaction.

if(your colour == their colour) Nothing happens.

if(their colour > your colour) They can attack you, but you cannot attack them.

if(your colour > their colour) They can attack you, and you can attack them.

The puzzling in the game, was made more interesting by adding a wall with an explosive barrel. And a lot of the game ended up revolving around that.
