The Last Byte: Serv-Bots Firewall Demo

This is the free demo of Serv-Bot's Firewall. You get the first 29 cycles on Normal difficulty, the full upgrade draft up to Epic, and the first fights with Greeb. Achievements, leaderboards, Legendary powers and the other difficulties are in the full game.

You are Serv-Bot, the last line between Greeb and the data towers. Threats rain down on the six towers you guard. Aim, fire, and detonate bursts that wipe out whole clusters at once; chain kills for combo bonuses, but watch your ammo, because every launcher has limited charges and a reload means a gap in the wall.

Every cycle escalates. Named waves like Ping Flood, Fork Storm and Crash Cascade bring new threats: fork bombs that split when you miss, bug pods that burst into swarms, USB bombers that carpet the towers. Then Greeb opens his arsenal.

Level up mid-run. Kills earn XP; every level offers a draft of upgrades across Common, Rare and Epic tiers: wider bursts, faster reloads, hardened towers, and ultimates that freeze the field, repair the towers, overclock your guns, or purge the sky.

Every tenth cycle, Greeb himself. Shoot his ship down, or beat him in the hack: a rhythm duel of arrow inputs where a perfect run reverses his intrusion. Fail three times and he breaches the firewall.

In the demo

• Cycles 1 to 29 on Normal difficulty
• Common, Rare and Epic upgrades, all four ultimates

The game is one night in the world of SIGNAL, Lerk Interactive's short-form series about the Grid, Gretta, and the hacker who came to tear its wall down.
