ROBO ARENA — Free 3v3 Robot FPS in Your Browser

What is it?

ROBO ARENA is a first-person shooter where cute robots battle 3v3 or 4v4. Your team scores a point each second only your robots stand on the core (two during the final 30-second core surge and overtime); first to 100, or the leader after 3 minutes, wins. If the trailing team is on the core when time runs out, overtime lasts up to 20 seconds.

Every hero has its own weapon and skills, and the training range teaches the controls. No install — jump straight into a match.

Fans of hero shooter games pick one of six robots here, each with its own gun, abilities and passive. A fallen robot drops its core chip; a teammate who grabs it first rebuilds it on the spot. Up to eight players join by room code, and an AI trial needs no sign-in, so it is one of the free FPS games to start at once.

ROBO ARENA is a first-person hero shooter for teams of three or four. Six robots make up the roster: Spark, Volt, Bloom, Pop, Bumper and Lens. Each has its own gun and damage falloff, a Q ability, an E ultimate that charges during the match, and a passive such as Spark's mid-air jump or Lens's double headshot damage. Every match starts on equal terms; hero mastery levels are cosmetic.

Two rules come from the robots themselves. A destroyed robot drops its core chip where it fell: a teammate who reaches it first rebuilds the robot there a second later at half health, while an enemy who gets there first scraps it and adds two seconds to the respawn. And two teammates who fire their ultimates within 1.5 seconds and 7 metres of each other link up: both effects last 50% longer and both robots take 25% less damage for 7 seconds.

Five of the six arenas are fought over one central core; Sky Terrace has three capture zones on a three-level rooftop.

Gameplay video and screens

Recorded from the live game — real play, not a mockup.

At 1:20 with the score 0–0, both teams are on the core, so it reads “Contested · Scoring paused” while an opposing Bumper (Kite) fills the view at point-blank range.

At 1:16 our team leads 2–0 and holds the core for +1 point per second; the feed reports that Coco scrapped Milo's core chip, which delays his return.

How to play

In the lobby pick a hero (←/→ or a hero card) and press Quick match. New? Try the Training range first.
Press Click to start to lock the mouse. When everyone in the room is ready, the match starts after a 3-2-1 countdown.
Head to the glowing core in the middle and hold it. Scoring stops while enemies stand there too, so push them off.
Shoot, use Q (hero ability), and fire E (ultimate) when it is charged. Use it within 1.5 s of a nearby ally for a combo ultimate.
You respawn 4 seconds after going down. An ally who steps on your dropped core chip rebuilds you on the spot.

Modes

Core control: Sunlight Yard, Cobalt Depot, Toy Plaza, Neon Arcade and Serpent Canyon. Only living robots inside the 3.7 m circle and within 2 m of its floor count, so robots on a bridge or ledge above it do not. A tie that survives overtime is a draw.
Zone control: Sky Terrace only. A and C sit on 2 m terraces and B in the sunken lane, under a footbridge that does not count. A zone you own keeps scoring 0.4 points a second even when nobody stands on it.
Quick match: Needs a GameNow account. You join a match on the same map, AI difficulty and team size that is under 40 seconds old, or open a new one, and bots fill every empty seat. The clock waits until everyone presses start, at most 15 seconds after the first.
Friend room: Invite friends with a 4-character code, which never uses I, L, 1, O or 0, or with the invite link. Up to 8 players and 8 spectators; AI takes empty seats and the host starts each round.
AI trial: No sign-in: 90 seconds of 3v3 on Sunlight Yard against Beginner bots, starting with a full ultimate. It ends at 0:00 with no overtime and stays out of account records and mastery.
Training: No clock and no score. T refills health, ammo and abilities and also charges allied bots' ultimates for combo practice; a panel shows accuracy, headshot rate and damage per second over the last 10 seconds.

Good to know

In the Training range bots never shoot back and there is no time limit. Press M to make them moving targets.
Sky Terrace is a capture map: each of points A, B and C you hold scores 0.4 per second; first to 100 wins.
Gamepad (standard layout): in the lobby ✚←/→ picks a hero, A starts Quick match, X opens Training. On the battle screen press A or START to begin.
You can rebind keys under Key settings in the Esc menu. The table shows the defaults.
