Undead Slayer Game

Undead Slayer drops you into an endless swarm of zombies that only gets faster the longer you last. Your hero attacks automatically, so the whole game comes down to where you stand: circle around clusters of undead, funnel them through choke points, and back off from anything that starts surrounding you.

Every enemy you kill drops a gem, and gems fill an experience bar that levels up your hero mid-run. Each level-up offers a choice of upgrades — new attacks like a lightning weapon, more damage, faster fire rate — so the build you end up with depends on which rewards you grab as the waves stack up. Survive long enough and a boss interrupts the grind, with attack patterns of its own to dodge.

Controls

• WASD or Arrow Keys — move your hero

Attacking is automatic — there's no aim or fire button, so movement is the only thing you're actually controlling.

Tips

• Move in wide arcs instead of running in a straight line — the undead spawn in behind you if you stand still or backtrack.
• Grab nearby gems before diving deeper into a crowd; a level-up mid-fight can turn a losing situation around.
• When a level-up offers a new weapon, take it over a plain stat boost early on — more attack types cover more angles than one attack hitting harder.
• You get one revive if your hero falls, so it's worth pushing one more wave near the end instead of playing it overly safe.

Undead Slayer suits short, replayable sessions — a few minutes at a time chasing a slightly better run than the last, right in the browser with nothing to install.
