Pro Tips & Strategies

1. Never stop moving. Standing still is how you die. Constant motion makes you a harder target for tanks and jets, and it lets you chain kills more efficiently.

2. Prioritize soldiers over civilians. Armed troops deal damage, so take them out first. Civilians are just free points — grab them when it's safe.

3. Use jumps to dodge projectiles. When you see a tank shell or incoming fire, a well-timed jump can save your run. Time it right and you'll sail over danger while still chomping.
