Federation 2 Simulator

Version 0.5 (2026-01-13)

For Federation 2 Community Edition

Federation 2 is based on the work of Alan Lenton, et al. This simulator consists entirely of completely original and reverse-engineered code.

How to use

• Load system zip archive
  • The simulator expects to see .loc, .msg, .xob, and .xev files for each planet & space map
  • All simulator data will be cleared when a new planet map is loaded
  • Nothing is stored on-server or uploaded anywhere: everything happens on your own computer
• Type commands in the input bar at the bottom
• Use standard Fed2 commands: n, s, e, w, look, inventory, get, drop, etc.
• Edit player stats in the sidebar (name, rank, stamina, money, slithies)
  • The player name turns blue when frozen
• Use the teleport feature to jump to any room number
• Set or delete variables manually from the "Variables" section

Known limitations

• Some event tags are not yet implemented
• Some vocab commands may not work correctly
• Some complex event chains may not execute properly
• Command parsing is still a little wonky and may not trigger the appropriate response
• Visual formatting may differ slightly from Fed2
• I'm sure there's more!

How to Report an Issue

• Message Ariapaxa in-game or on Discord
• You can also see the changelog, to-do list, and submit a patch request to the SourceHut repository
