The Ultimate PC Splitscreen Tool

Nucles Co-Op is a PC Splitscreen Tool for Windows that allows split-screen play on many games that do not initially support it.

PC Splitscreen Tool

Currently Supported Games:

  • Aliens: Colonial Marines
  • Alien Swarm: Reactive Drop
  • Borderlands
  • Borderlands 2
  • Borderlands: The Pre Sequel
  • Don’t Starve Together
  • Gas Guzzlers Extreme
  • Left 4 Dead 2

What kinda works:

  • Saints Row 3 (doesn’t connect to other instances, but plays independent campaigns)
  • CoD: Black Ops 1 (requires a giant setup I havent written out yet, I`m working on automating it)

What I broke/doesn’t work:

  • Left 4 Dead (only the first one, will be back on Alpha 9)
  • Synergy (supported was added by d1maxa, I tried fixing but I ended up breaking it more. Will research and bring back in a next release).
  • Mouse support (in games that need Force Focus, Mouse support is completely broken)
