Take a seat
Each player presses a button on their own controller to join and takes a spot on the screen. Pick a layout that fits your players.
Launch and connect
Press Launch: Nucleus opens one copy of Guncraft per player and lays the windows out on your screen. Then link them in game, usually one player hosts a LAN or online session and the others join it. The handler notes say how.

Handler notes

Make the game windowed before trying split screen.

You will get a error on start, ignore it, the handler works on LAN. Go into edit character and change your LAN name and anything else you need. Now use the LAN option to host/join each other. You can press ctrl+t twice to fix aspect ratio if you want (you will get black bars).

About Guncraft

Block and Load!! Marrying the addictive nature of block building sandbox games with the speed and competition of modern first-person shooters, Guncraft takes voxel-based gaming to a whole new level. Players can create maps and arenas based on anything imaginable and, once complete, can utterly destroy them with bullets, bombs, grenades, tanks, helicopters, gunships, and much more. In the heat of battle, soldiers can create custom blockades and fortresses instantaneously. Watch out – just when you think you’re safe, enemies can tunnel through walls and dig through floors to ambush you from behind, above or below! In addition to Deathmatch and Team Deathmatch, Guncraft offers over seven outlandish game modes like Lava Survival and Spleef, plus tons of custom load-outs, perks, weapons, vehicles and more. Even better, the core crafting mechanics of Guncraft are available throughout every aspect of the game, enabling players to build maps, characters, and weapons on the fly, then decimate them all to take down enemies.
