aMazing Assassins gives you two heroes who can work together to clear dungeons that are growing zombies. You can cloak/switch between the two  to use their differing skills almost whenever you like. One wields a dagger, the other shuriken stars. The zeds in the dungeon are almost invincible if they see you, so the only real option is to creep up behind them and take them out. Sort of multi-character pacman with a stealth aspect to it. When zeds catch sight of you, they will rage and chase you. You can only escape by either losing line of sight for a long enough period of time, or by making it into the escape tunnels.
