Grab guns and bolt them onto your ship. Keep going until the screen is nothing but your bullets. Spend gerbs in the Hangar, save the babe, and come back for more.
Each player presses A on a controller (or Space on the keyboard) to grab a ship. Phones: scan the code, then press ROLL.
Fly: arrow keys / WASD, drag with a finger or the mouse, or the left stick. Your guns fire by themselves.
Grab crates. Each one is a new gun or part. The game freezes, zooms in on your ship, and you pick where to bolt it on. Arrows or the stick move it, Q / E or the bumpers turn it, Space or A bolts it on. Guns never come off on purpose. You just keep adding.
Get hit and parts get knocked off. Lose your cockpit and the whole ship falls apart. The junk floats around until your grabber arm reels it back in. Fly close to it.
Gerbs are the coins. Spend them in the Hangar after every boss: level up your guns and buy your way across a skill web with thousands of upgrades.
Dodge roll: Space, right-click, the blue button, or A on a controller. Bullets can't touch you mid-roll. Nuke: X, the red button, or B.
BEAM: B, the BEAM button, or Y. Once it's charged up, push it. After three seconds of alarms, every gun on your ship turns into an enormous beam for twelve seconds. It melts bullets and sets the ground on fire. SLAP: F, the SLAP button, or X. Bolt on enough grabber arms (5) and every arm reaches out and slaps something. It's mostly disrespectful, but it still hurts.
BRAG: O, the camera button under pause, or Select on a controller. It draws up a blueprint of your ship to save and send. The camera also watches every fight, and after each boss you get the three craziest photos it took.
Shields: hard-light plates can't break and cover the cells around them. Bubble shields cover a lot more but shut down for a few seconds after too many hits.
Your screen cracks when you get hit, and it gets worse. The second it cracks, the SPACE SEMI pulls up. Fly in the back: the crew patches you up and bolts on something good, but the enemy bulks up the whole time you're in there. Come out swinging.
