A PARTICLE MUST SURVIVE IN A SUBATOMIC WORLD SUBJECT TO STRANGE PHYSICS LAWS.
ONLY ONE WEAPON: COLLIDE THEM OUT !
Collide is the name of a synthetic particle designed in the laboratory.
During an experiment on atomic nuclei and subnuclear particles, a big collision opened a black hole, which makes Collide vanish in antimatter. Scientists have to close this gate before it's too late and so send a second twin particle in rescue of Collide to trigger a second collision in order to close the gate. Thus begins the story.
CollideOut is an arcade game with an infinite procedurally generated landscape.
