Tips and tricks
- Prioritise the threat that will hurt you soonest, not the one that is closest or biggest. Fast enemies before slow ones, shooters before melee.
- Headshots, weak points and combo multipliers are where high scores live; once survival is comfortable, start hunting for them.
- If there is a reload, reload during quiet moments — never in the middle of a wave.
- Learn the spawn points. Most levels reuse the same few entry points, and knowing them turns panic into routine.
- Because this is a Shooting game, aim before you fire, and fire in short bursts.
