About this project

Campaign co-op for 2 to 4 players sharing one squad, built from zero on the game's own lockstep multiplayer layer (a DLL loaded by FTSE), MIT. Every player can order every squad member; the host's campaign is played and its save is copied to joiners, who can drop in mid-mission. Synced on top of the lockstep: conversations, quest variables, shops (pausing nobody), recruiting, level-ups, looting, turn-based combat (Individual and Squad), the host's settings, the world map (the host travels, everyone sees it, map pings in each player's colour) and random encounters; a drift check corrects positions, HP, inventories, equipment and the entity table without a reload. Bot tests drive 2 to 4 real game copies on one PC; played by people on two PCs on one home network. Needs GOG 1.27 and FTSE 0.60a. Beta v0.10.4-beta (2026-10-30). See games/fallout-tactics.
