Four ways to fight, each in a few minutes: solo or with a team, against the clock or to the last robot standing.
Ten robots wake up in a decommissioned data center, and only one walks out. Break crates for upgrade chips that make you stronger, keep clear of the nanobot swarm as it closes the arena, and be the last unit online.
Data cores rise out of the mine in the middle of the arena, but a core in your hands counts for nothing. Carry it home, upload it into your team's vault, and keep the other team out of it. Twelve cores banked start the exfiltration: hold your vault until it runs out and the match is yours.
Two teams fight over the arena's uplink nodes. Every node your team holds fills its sync bar, and holding more of the arena pays far better than trading nodes one for one. The first team to 100% sync wins.
Each team has a core behind two firewalls, one on each lane. Bring both enemy firewalls down and their core opens; destroy it and you win. Ore grows in the fields between the lanes, and your team spends it together on the build wheel.
