About this project

No campaign co-op mod found. A 2025 Steam reply names a "CoD 1 Cooperative Mod" with no link or author; no build was found. The ModDB "Call of Duty 1 Splitscreen PC v1.1" file is a 318-byte multiplayer splitscreen launcher, not campaign co-op. Research and reverse-engineering notes for the 1.5 singleplayer exe (4 server client slots kept, network transport stripped to loopback) and a per-mission script survey are in games/call-of-duty. The native networking part is open for someone to take on.
