How the game changes
- Three main episodes start at Barracks, Power Station and Maintenance respectively. The two secret maps form a separate optional episode that cannot be selected alone.
- Selected keys, weapons, armor and powerups become randomized checks. Map exits award fixed completion events for the goal, not an additional random reward.
- The item pool includes map access, map-specific keys, computer maps and S.T.R.A.I.N. weapons such as the sawed-off shotgun, NFG and psychic blaster. Backpacks can be combined or split into ammunition-specific capacity upgrades.
- Five goal modes support every enabled map, a chosen count, a random set, specific maps, or a count plus specific maps. The default requires every enabled map.
- Combat difficulty, monster and pickup shuffle, music, mirrored maps and starting computer maps are configurable. Advanced tricks and death-dependent routes are separate settings, disabled by default.
- DeathLink is optional. EnergyLink is enabled by default, converting redundant received items into shared energy for supplies; named pools can restrict who shares that energy.
Before you start
- This is an additional campaign, not a separate Steam game. The Steam link, artwork and review total describe the DOOM + DOOM II base collection. You need your own DOOM2.WAD plus the separate STRAIN.WAD and STRAIN.DEH files.
- Install doom2_strain.apworld in both Archipelago's custom_worlds folder and APDoom's games folder. Keep the package intact: its STRAIN_ExtraAPData.wad supplies supplementary interface graphics. Select DOOM II - S.T.R.A.I.N. for the slot.
- Use the original campaign files from the linked repackaged archive, retaining its notices. Place STRAIN.WAD and STRAIN.DEH beside APDoom. The old DOS installers are historical extras and are not needed for this route. Do not substitute a different source-port-fixed edition without compatibility guidance.
- Use APDoom 2.0 with the July custom-world loading hotfix and Archipelago 0.6.3 or newer. Prefer original DOS DOOM2.WAD data. The dated APWorld version is not the client version; unrelated gameplay mods are not covered.
- Keep starting ammunition capacity at its defaults: 200 bullets and 50 each for shells, batteries and rockets. Lower limits are explicitly warned as potentially logically unsafe. Leave advanced tricks and death logic off for a conservative first configuration.
- Start with a fresh client directory and back up saves. Do not mix old 32-bit client dependencies with APDoom 2.0 or change a room's world package during a campaign without compatibility guidance.
- The package, shared generator rules and required-file inventory were reviewed, not independently played through. Windows and Linux/AppImage are documented client routes. The original campaign's co-op support does not establish same-map co-op support in this integration.
