About
Old game.
Tiny server.
Twenty-eight years ago, the prison transport Vortex Rikers went down over Na Pali. You wake up in the wreckage – no briefing, no weapon, just a flashlight and the distant sound of something Skaarj-shaped moving through the corridors. That opening is one of the defining moments of '90s PC gaming, and this server exists to relive it, together.
It runs on a Raspberry Pi Zero 2, a computer about half the size of the game's original CD case, held together with JCoopZ for proper coop admin tooling and AkimboMM for some good old dual-wielded excess. No anti-cheat, no matchmaking, no monthly patch notes. Just the campaign, played at whatever pace a few friends and a slow evening allow.
What to expect
- Ancient Nali ruins
- Skaarj ambushes in narrow corridors
- Custom weapons waiting where the stock ones used to spawn

Why this exists
Twenty-eight years is a long time to carry a game around. I first got my hands on Unreal in the beginning of 1999, and it wrecked more all-nighters than I'd like to admit – including a fair number of Geography lectures at university that quietly lost out to Na Pali. The one I still tell people about: waking up at 4 or 5am local time just to run the campaign with a coop group from Australia, because that was the only overlap our time zones allowed.
This server is, in a very real sense, still that same obsession – just with better hardware and considerably less sleep deprivation.

What's running
Built for the campaign
JCoopZ
Proper server-side admin tooling – player-targeted item grants, kicks, and the housekeeping a coop server actually needs.
AkimboMM
Dual-wield your AutoMags into MultiMags. Four ammo types, one alt-fire away from ChAoSS.
Custom Arsenal
A modified Raketenwerfer (Multi Rocket Launcher) and Schrotflinte (Shotgun), swapped in automatically for six stock weapons wherever they'd normally spawn.
Field recordings
The soundtrack
Played through UnrealAMP, our little Winamp-inspired jukebox.
Original score
Alexander Brandon · Michiel van den Bos · Andrew Sega · Dan Gardopée – tracker music, 1998.
