Game description (written by KoiArcade)
Zombie Mission 11 is a 2 player co-op platformer from the Zombie Mission series. This time the zombies have reached the sea: pirate zombies are attacking the beach and capturing the mermaids, and sea creatures have turned into zombies too. Two heroes in diving helmets fight through the levels together on one keyboard, using melee hits, guns, grenades, wall jumps and a special attack that charges up on the SP bar.
The game's own description says the 11th part adds new mechanics, new characters and vehicles.
How to play
- 2 players share one keyboard.
- Player 1: move with W A S D, hit or shoot with C (hold C and release for a mega hit), grenade with V, jump with W, switch weapon with Q and E, special attack with Q + E when the SP bar is full.
- Player 2: move with the arrow keys, hit or shoot with L, grenade with K, jump with Up, switch weapon with O and P, special attack with O + P when the SP bar is full.

Tips
- Keep moving and fight at the edge of a group instead of the middle.
- Reload during quiet moments rather than mid-fight.
- Pause for a second before a tricky section and watch the hazard pattern first.
