In the aftermath of an Alien Invasion, the player assume controls of two commandoes, Emmy and Fred (and on 3-player mode, another guy named Chris) to clean the streets of alien forces before travelling to the unnamed alien leader's underground base, destroying all the alien lieutenants and everything in their way before the final confrontation.
… yeah, it's that kind of game. All of it.
The game is operated via a two stick system, for simultaneously controlling the characters and aiming shots, the latter granting an option for rapid firing. Oddly enough unlike other arcade releases at the time, continuing after running out of lives will send the player back to the start of the level.
Unrelated to the movie.
Go Down! Good Luck!
- Absurdly-Spacious Sewer: The second stage is set in one of these. As the game is played from a top-down perspective, you can see the sewers you spend most of the stage wading in is roughly the size of a lake.
- Bat Out of Hell: Giant bats are another recurring enemy type, and they're expectedly faster than regular enemy mooks.
- Blob Monster: Occasionally, the sewer stage will have green blob-creatures rising out of the sewage. Like every other enemy in the game they appear in large numbers, can assume a humanoid shape to attack, and dissolves when killed.
- Bottomless Magazines: Your default machine-gun, and it doesn't even need to be reloaded! You can just hold on the firing button and run amok for the entirety of the game.
- Checkpoint Starvation: If you run out of credits, it's back to the beginning of the level.
- Cyber Cyclops: The Final Boss pilots a gigantic, one-eyed robot as his weapon to battle. His lieutenants in contrast simply fight you while seated on their thrones.
- Dem Bones: The second stage have skeletons appearing before the sewer's entrance, for some inexplicable reason.
- Easily Thwarted Alien Invasion: Despite the game's premise of being set after aliens took over our cities, the alien forces are hardly competent at their jobs. Most of them simply loiters around and taking potshots, and your characters easily destroy them in massive numbers each stage.
- Excuse Plot: There are aliens, and you need to put a bullet in each and every one of them.
- Everything Trying to Kill You: If there's a moving object onscreen and it's not one of your fired projectiles or the other player, it's an enemy.
- Flunky Boss: All the bosses, since they're stuck on their seats, will instead summon hordes and hordes of mooks from all sides.
- Mecha-Mooks: The game's enemy design seems to alternate between organic foes to robots, though robot enemies are no less durable and dies with similar ease.
- One-Word Title: Bullet, which is what you spend the whole game dispensing at everything that moves.
- Palette Swap: Many of the mooks are, unsurprisingly, recolored versions of each other. Taken to the extreme, with every single boss except the last one being made from the same sprite, recolored over and over. Though it's likely justified since this is an old game.
- Rat Horde: The sewer stages have plenty of rats appearing alongside regular enemies. One shot with your weakest firearm is enough to kill them and they do pathetic damage if they get past your defenses, but these rodents tend to appear in waves.
- Stationary Boss:
- The alien generals - all of them - are fought while seated on their thrones, where thery will either sic their mooks on you, summon turrets, or try blasting projectiles from their seated positions. Occasionally if you get too close to them, they'll then release a projection of themselves capable of hurting you.
- Meanwhile, the Final Boss - despite being a scary-looking robotic monster, is tethered to the ceiling by a series of wires.
- Stripperiffic: Emmy, the sole female character of the game, have no issues strutting before legions and legions of enemies clad in a sleeveless leotard that exposes her navel. It sounds sexy, but then you remember there's the sewer stage where your characters wade across waist-high filthy water.
- A Winner Is You: Another early example; after the final stage, you're then shown a three-second clip of your character(s) walking on the streets, with the words "CONGRATULATIONS [INSERT NAME]" in caps. Then... you go back to the first stage. Have fun!
- Zerg Rush: The tactic of pretty much every onscreen enemy, where they show up in waves of multiple dozens trying to overwhelm you. Do NOT expect the level screens to contain less than ten onscreen enemies at any point.
