Zombie Mission 13

Grab a friend and fight through a zombie-packed lab—Zombie Mission 13 gives you two guns, two health bars, and zero mercy.

Zombie Mission 13 drops you and a partner into a side-scrolling lab overrun with the undead. Player one uses WASD and C to smack zombies, while player two handles arrow keys and L. Simple, right? Then a bloated zombie explodes next to you and your buddy is screaming about reloading. The game keeps throwing new enemy types—spitters, shielded brutes, things that charge—so you're constantly swapping between guns with Q and E, lobbing grenades with V, and praying the special attack bar fills before you're cornered. I played a few rounds solo and it's fine, but the real magic is two-player. There's a moment in the second lab area where you have to split up—one player stands on a switch while the other clears a hallway. My partner kept getting swarmed because he forgot the mega hit (hold C and release) does way more damage. We died like six times before I yelled at him to stop button-mashing. That's the charm: it's not a brainless horde shooter; you actually have to coordinate reloads, cover each other's blind spots, and manage limited ammo. The visuals are clean enough to tell a regular zombie from the armored one that eats your bullets, and the sound design—low groans, squishy headshots—keeps tension high. It's free, it's unblocked, and it works in a browser. If you have a friend and twenty minutes, this is a solid co-op pick for a school lunch break. Just don't expect to beat the later levels without yelling at each other.

Hold C and release for a mega hit—it clears groups faster than swinging normally.
