In it, you play as a Waddling Head who has to fight a army of monsters that come from the top of the screen. However, you don't get any points by killing them. Instead, you must collect the boxes that appear at random locations in the screen, and every time you pick one of them, your current weapon changes.
On April 1, 2011, Vlambeer announced
they had fixed a supposed “bug” in the scoring system, which was now tied to enemy kills and not crates, and also made the discgun not deadly for the player. To great surprise, it turned out real, but the original version was obviously restored for download the day after.
It will be re-released on the Nintendo Switch in April 2019, with added local co-op and versus modes.
This game contains examples of:
- Bottomless Magazines: The weapons never run out of ammo.
- Crate Expectations: The objective is to collect them.
- Deadly Disc: The Discgun. It bounces off walls and can kill you too. The April Fools' version has a non-deadly Discgun.
- Elvis Impersonator: One of the unlocked avatars.
- Endless Game: The game will last as long as you don't die.
- Flash of Pain: When enemies get hurt, they flash red.
- Gatling Good: The minigun fires out enough bullets to clear anything and everything that you're pointing in the general direction of within a second or two. The knockback can be daunting to newcomers, but it is completely neutralized by simply running in the direction you're shooting. Getting one in SFMT or Ambush when your screen is flooded with enemies is a prelude to a swift bout of room-clearing.
- Guns Akimbo: The Dual Pistols. Too bad they're the lamest weapon a crate can give you.
- Lava Pit: Falling into the pit of fire will, of course, spell instant death.
- No Ontological Inertia: A rare player case. When you die, any mines you have set up immediately explode.
- One-Hit-Point Wonder: It only takes one hit to do you in, whether it is running into one of the enemies or getting hit by a disc from the Disc Gun.
- Short-Range Shotgun: To the point where the pellets suddenly vanish after only a few feet.
- Shotguns Are Just Better: I can't make up my mind, okay? They're all good.
- Turns Red: If a enemy drops on a Bottomless Pit, it just respawns, red and faster. Don't let too many enemies do this, or else...
- Video Game Flamethrowers Suck: Averted. The flamethrower is excellent for quickly killing all enemies on screen.
