Slipstreak

Speed is your damage
The faster you're moving, the more your gun hurts. That's the whole hook. So you're not hunting for cover, you're hunting for the next wall to kick off, the next ramp to slide down, the next line that keeps your speed up while you put rounds in someone.
If you've played Quake, CS surf, or Titanfall, you already know the feeling. If you haven't, the speedometer in the corner tells you when you're doing it right.
The movement
It's a ladder, and every rung is faster and harder than the last:
Bhop — hold jump, strafe and turn together, keep your speed off the ground.

Landing slides — slide the moment you hit the floor off a big drop and turn the fall into forward speed.

Wall touches — tag a fresh wall for a boost. Same wall twice gives you nothing, so keep reading the room.

Wall kicks — jump the instant you touch a wall and bounce between them without losing a step.

The boosts get smaller the faster you go, so you're always chasing the cap instead of blowing past it. The speedometer flashes green when a trick lands.
Guns and perks
Primary, sidearm, perk. The VELO scales its damage off your speed. The DMR one-shots headshots if you can land them. Attachments change how a gun feels, never what it does to the other guy. Seven perks, and nobody can see what you picked, so there's nothing to hard-counter. Run what you like.
Powerups
Juggernaut, double damage, and adrenaline sit out on the map. They don't drop from kills, so nobody just snowballs a lead. You go get them. So does everyone else.
Deaths
Bodies ragdoll with all their speed still on them, so catch someone at the top of a bhop and they'll cartwheel halfway across the map. You don't skip it either — the camera hangs back and lets you watch.
Playing with people
2 to 8 of you, over Steam or on a LAN. Proximity voice is in, and it sounds like a 2013 Xbox party on purpose — muffled and a little crunchy. First to 20, or whoever's ahead when the timer runs out. Then run it back.
The maps
Built around the movement from the first block: alleys to wallrun, canyons to kick across, a trench to slide through, towers to jump off and convert the fall. More coming.
It plays fine if you just want to run around and shoot. It goes deep if you want to learn the tech. Either way you'll die laughing at least once.
