How the game changes
- Campaigns: 18 Half-Life missions, plus 12 Opposing Force and 6 Blue Shift missions when included. Expansions require the player's local installation; the Archipelago World name remains Half-Life.
- Checks: map/chapter progression, optional health and armor chargers including Xen healing pools, and first weapon/equipment discoveries. The supplied data contains 252 Half-Life, 97 Opposing Force and 64 Blue Shift entries before configuration filtering; the README's Opposing Force total is lower.
- Items: mission and weapon unlocks, campaign armor, optional Long Jump, flashlight/night vision and melee throw, plus supplies and four regular traps. Starting melee/mission and unshuffled equipment have explicit handling.
- Goal: complete the chosen number of non-finale missions in each included campaign to open its finale, then finish every included finale. Required counts clamp to available missions; Half-Life alone is the default.
- Logic: strict weapon groups, always-required equipment, per-map progress and alternate first-weapon sources. A startable mission is precollected, and excluded campaigns/intros/check families leave the graph.
- Guidance: mission panels, chat commands, tracker/menu, nearest-check hints and customizable binds. Local warp saves preserve visited-part state; missions remain repeatable from the hub.
- Options: campaign selection, completion seals, chargers, intro exclusion, equipment shuffling, melee/ally-drop choices, trap percentage and optional DeathLink with outgoing amnesty. Removed ammo relief has no effect.
Before you start
- Evaluated release v0.3.1, published October 2, 2026, contains World 0.3.0 and requires Archipelago 0.6.7+. Select Half-Life in YAMLs and the Launcher; the upstream now calls this retail variant Half-Life Trilogy.
- Requires the current Steam anniversary Half-Life on Windows, not steam_legacy, WON or Xash. Optional Opposing Force and Blue Shift must be installed in the same Steam library. Use Half-Life Client /install, connect it to the room, then launch with -game hlap. The installer mounts expansion files locally from those installed games.
- Back up hlap/SAVE before uninstalling. Warp points are local and derived from seed/slot; they are swept on goal or uninstall. Progression unlocks rebuild from server history, but pending checks and victory lack a durable acknowledged retry path. Stay connected when completing a mission or finale.
- The initial history batch restores unlocks without replaying filler or traps, including one-shot rewards received while offline. One-shot delivery is not fully protected across priority messages and process restarts. The old experimental ammo_relief option is now inert.
- The native DLLs are SDK-based and the package does not include a complete licence/notice inventory. Valve permits free SDK-based distribution subject to licence conditions; this review records missing companion evidence without determining infringement. Original game/expansion assets are read from the local install; no full game or DLC archive was identified.
- Source/package correspondence covers 46 readable/resource files; native DLL inspection covers PE metadata, imports and AP markers. Fourteen supplied test files contain 293 test functions, including World-specific prerequisite and generation-profile assertions, client slot-data parsing, bridge and installation contracts. No target tests, build or game were executed, and full binary correspondence was not established.
