How the game changes
- Item pickups become locations, with map icons identifying remaining checks, including those carried by enemies. Duplicate-location compression is enabled by default to reduce repeated nearby pickups; chemicals and the starting wrench are separate optional checks.
- Access cards, mission objects and audio logs control progression. Keypads require the relevant log or email instead of remembered codes, although hackable keypads can still be hacked. The tutorial keypad is exempt.
- Statistics, technical and weapon skills, psi tiers and individual psi abilities are shuffled by default, as are OS upgrades. Disabling character randomization restores cyber-module spending, with a respec machine available to rearrange the build.
- Enemy randomization, elite enemies and randomized replicator stock and prices are enabled by default. Elites add tougher encounters and extra loot. Turning enemy randomization off changes the intended early- and late-game balance.
- Four goals end the run after defeating Shodan, defeating the Many, reaching the Many's level or reaching the Rickenbacker. The Science Access Card is included in the default starting inventory.
- The transmitter requires all four pieces of its art code. Optional code-art randomization moves them around Recreation or more widely across the ship. Optional DeathLink shares deaths with participating Archipelago players.
Before you start
- Install both ss2.apworld and Archipelago.kpf from release 0.5.2. The APWorld manifest declares Archipelago 0.5.2, the README says 0.5.1 or newer, and the supplied YAML template requires 0.6.7; use 0.6.7 or newer to meet every published version declaration. Both the player and seed generator need the APWorld. Never update the mod or world in the middle of a run.
- This listing covers the Windows 25th Anniversary Remaster. Put Archipelago.kpf in the game's mods folder and enable it when starting a new game. The classic edition uses a different .7z package, SS2Tool and SCP beta8; do not apply those classic instructions to the remaster. Linux, Proton and console integration support are not established here.
- Start System Shock 2 Client from the Archipelago launcher and connect before starting the game or loading a save. For the remaster, select the Nightdive Studios/System Shock 2 Remastered folder under Windows Saved Games, not the installation directory. Changing host.yaml paths requires restarting the client.
- Received items only begin arriving after leaving the airlock and collecting the first location. Keep progression items: losing one can require recovery through the game's console or Archipelago. With chemical checks enabled, the first vanadium and two antimony items are progression-critical.
- Back up saves and use a dedicated campaign per room and slot. The inspected bridge compares a shortened seed identifier, not a complete seed-and-slot identity. Its local files are cleared on client shutdown; do not assume offline checks are durably preserved or that it prevents every wrong-save combination.
- The inspected client can resend already observed checks, and malformed bridge data can repeatedly enter its error handler. If synchronization reports errors, follow the maintainer's restart-and-reload guidance rather than continuing unchecked. These code-review concerns have not been reproduced in a game session by Panludia.
- Native shared-save co-op is not established for this integration, even though the base game offers multiplayer. A published release and inspected scripts do not constitute a security certification or an independently completed campaign.
