Null Reference Exception

Null Reference Exception is a 3D bullet hell game set in an advanced laboratory. You play as an AI from the distant future, taking part in combat simulations against waves of enemies and timed bosses. You can repeatedly train, swap and combine modules, and refine your setup.

Combat training

Start a simulation to fight ongoing enemy waves. Bosses must be defeated within a time limit. Combat training also provides enhancement points as a byproduct.

Modules and enhancements

Choose modules for your player and combine them to create different setups. You can unlock locked modules with achievement rewards or achievement points. The Enhancement Center lets you spend enhancement points to improve your stats; all enhancements are currently passive.

Achievements

Achievements track progress across different content. Their rewards can include achievement points or module unlocks.
