An early 16-player co-op mod arrives for Marvel's Spider-Man 2 on PC

PC Brazil Team has published an early build of the PC Brazil Multiplayer mod for the official Nixxes PC port of Marvel's Spider-Man 2. The mod adds networking, for two-player sessions or an open-world group of up to 16 people at once.

The current build is aimed at exploring New York together and clearing random street crimes. The story and the extra activities are still in closed testing. Most story missions cannot be finished in co-op yet, though a few can be completed without a critical failure. The authors warn that this is a very early stage: expect bugs, unfinished netcode, and crashes.

Reported technical problems include lobby-menu freezes, sync failures, and ability bugs that stop a joining client from switching symbiote branches. To avoid corrupting the main saves, co-op progress is stored separately and read from an internal mp-saves folder.

The script is installed with the Overstrike utility, and the launch parameter -scripts has to be set in the game properties or in the Steam client. There is no direct connection through official servers. Players need port forwarding or a virtual LAN — Radmin VPN, Hamachi, ZeroTier, or Tailscale — even when the invite goes out through the Steam friends list.

The first public version went out on 9 October, and on 10 October 2026 the authors shipped the PreRelease2hotfix for basic network-lobby problems. Compatibility with other mods is not guaranteed.
