Edge writes: "The game's hook is that it is wholly co-operative: the two players can only destroy enemies of their own colour and are vulnerable to those of the opposite. Like Geometry Wars, it possesses an expansive bestiary of enemies – some foes make a bee-line straight for the player, others emit pulses of colour-coded shrapnel and yet more lay eggs which hatch if not swiftly destroyed.
There are some neat touches in the way that Schizoid is structured in order to crowbar weaker players through the campaign. The team's ten lives are refreshed every seven levels, marking each new tier. When playing through a tier again, you automatically skip the levels in which you have already received a gold medal and you can also choose to grind away on a single stage until you've made the grade."
