Tips and tricks
- Move between shots. Many shooters make you an easy target only when you stand in one place.
- Aim first, then shoot. Spraying costs time or ammo and rarely helps; a single well-placed shot almost always beats three rushed ones.
- Prioritise the threat that will hurt you soonest, not the one that is closest or biggest. Fast enemies before slow ones, shooters before melee.
- Learn the spawn points. Most levels reuse the same few entry points, and knowing them turns panic into routine.
- Because this is a Math game, estimate first, then calculate — most maths games reward speed as much as accuracy.
