Ultimate Down

You move with WASD and aim with the mouse, shooting at the waves of zombies that close in from all sides. The main goal is to survive each round as the number of enemies steadily increases. You can switch between a handful of weapons using the number keys, and you have to remember to reload manually. The pacing is relentless, with little room for error as the horde grows denser. It feels tense and immediate, a test of your ability to keep moving and shooting under constant pressure.
