Hold the grid against waves that learn. Dodge snipers, break guardian shields, survive the anomalies, and choose whether a corrupted upgrade is worth the price.
Enemies arrive in waves. Clear a wave to pick an upgrade. Bosses appear every fifth wave and alternate between the Core and the Hive Mind. Quick kills build your score multiplier; taking a hit resets it.
The threat meter reacts to how you play. Clear waves fast without taking damage and more elites, anomalies and specialists show up. Struggle and it eases off. Enemies never just get tankier. From wave 11 they start using new tactics.
Gems add score. Spread, Laser and Rapid are timed weapon mods that stack. Shield cells, repairs and bombs do what they say. A gold star is a rare upgrade, applied instantly. From wave 3 the upgrade picker may offer a corrupted upgrade: a huge boost with a permanent cost.
