Start a room on the TV. Everybody goes to the address on the screen (or scans the code) and types the 4 letters. You get a tank.
On your phone, pull back like a slingshot: the arrow is where it goes, longer is harder. Fine-tune with + and −, or drag the angle dial. You get two moves a turn (◀ MOVE ▶) before you lock in. Pick a weapon (nobody else can see which), then LOCK IN.
When everybody's locked in (or the timer runs out), all the shots go at the same time. You can switch to taking turns, or turn the timer off, in the lobby.
When the dirt gets too flat or too low, everybody falls through. First a floor that's just a bit (the spa, a board game, two giants flexing...), then the next real floor.
Land on your boat. Miss it and you sink and explode somewhere off screen, then drop back in next turn. Maybe into the water again.
Some weapons are other people's problem: the Coach's Whistle turns everybody else's shot into a whistle (but the gym teacher stands next to you, sweating). Hamsters. Dogs. Unicorns.
Points: damage and kills. Pride: weird weapons earn it; coats, sweat and getting insulted by Will's mother cost it. Milk intake: sitting in Thin Milk. At the end, a wheel decides which one mattered.
You always hold ten, out of over a thousand (raining geese, homing Bloody Marys, a pile of mannequins, Lurch Deths, Scottland Hard...). Fire one and something new takes its place.
Gerbs are for your tank: a bigger tank, more explosion, more liquid, better treads, and perks like Always Sweating and Shocks Neighbors. You start with 1,000 and earn more by doing damage. Whatever you buy is secret.
Heckle the living from your phone.
