Grab weapons, use cover, survive the waves.
Weapon pickups (crates with a gun icon) swap your current weapon and give it ammo. Health pickups (crates with a heart) heal you. Losing all your health costs a life; lose all 3 lives and the mission ends. Each wave brings more raiders โ clear a wave for a short breather before the next one drops in.
Doodle Strike is a top-down arena shooter built around endless wave survival rather than a match against other players. You get three lives and a deliberately small arsenal -- an unlimited-ammo pistol you always have, plus a rifle and a shotgun you'll need to pick up and manage ammo for -- and the raiders keep coming in escalating waves until you run out of lives.
That small, ammo-managed weapon set is what separates it from Doodle Warz's arsenal-and-progression approach: there's no weapon-tier unlocking here, just three tools with real tradeoffs -- the pistol's infinite ammo as a fallback, the rifle's fast fire rate against a limited 60-round supply, and the shotgun's five-pellet spread that's devastating up close but burns through its 24 shells fast. Using cover well matters as much as aim, since waves only get more numerous as you survive longer.
Save shotgun shells for when raiders are genuinely close -- its wide pellet spread wastes most of its damage at range, so firing it early just leaves you without it when a wave finally closes in around you. Don't be afraid to retreat to your infinite pistol between waves to conserve rifle ammo; the pistol won't one-shot much, but it never leaves you defenseless the way running dry on rifle rounds mid-wave will.
You start with three lives. Losing all of them ends the run, so surviving a late wave often comes down to how carefully you've protected your remaining lives earlier in the match, not just your aim in the moment.
Yes for two of the three weapons -- the rifle carries 60 rounds and the shotgun 24 shells, both of which run out. Your starting pistol has infinite ammo, so it's always a fallback once the other two are dry.
It's wave survival against AI raiders, not a player-versus-player match -- waves keep escalating in number and difficulty the longer you last, and the goal is simply to see how many you can clear before running out of lives.
