Usurper Reborn - a text-based RPG with native Linux builds (x64 and ARM64), runs great on Raspberry Pi

Usurper Reborn is a modern C# recreation of the 1993 BBS door game "Usurper." It's a text-based RPG with turn-based combat, a 100 floor dungeon, NPC world simulation, and online multiplayer. Built on .NET 8, self-contained binaries for Linux x64 and ARM64.

Linux details:

  • Native x64 and ARM64 builds. No Wine, no Proton, no Mono. Self-contained .NET 8 binary, zero dependencies.
  • Runs in any terminal emulator. Alacritty, kitty, foot, WezTerm, xterm, whatever you use.
  • Ships with a bundled WezTerm option if you want a preconfigured experience, but it's completely optional.
  • ARM64 build runs on Raspberry Pi. I've tested it.
  • The online multiplayer server runs on Linux (Ubuntu on AWS). You can self-host with Docker (docker compose up -d) or run the binary directly.
  • SSH into the public server right now and play: ssh usurper@play.usurper-reborn.net -p 4000 (password: play)
  • Works with MUD clients too (Mudlet, TinTin++) via raw TCP on the same port.
  • GPL v2 licensed, source on GitHub.

What's the game?

11 classes, 10 races, 100 floor dungeon with 8 themes, 7 endgame god bosses, 4 recruitable companions, NPC permadeath, faction system, player housing with upgrades, a player-driven settlement, guilds, tournaments, New Game+ with prestige classes, and a world that simulates autonomously -- NPCs form relationships, get married, betray each other, run for king, and die permanently.

Online multiplayer lets you group up for dungeon crawling, join guilds, fight world bosses, and chat. Or play entirely offline.

Screen reader accessible too (--screen-reader flag) if anyone needs that.
