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 Codename Cure 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.

A PC that can run 5 copies
Each player runs their own copy of Codename Cure, so the PC carries several times the usual load. Lower the graphics settings if it struggles. Performance tips

Nucleus links the windows through the game's own LAN or online mode; the handler takes care of it.

Handler notes

The game has no controller support on the menus.

Start a local server on the first instance. After creating a game on the first instance accept the prompt to start others and join with the server browser in the LAN tab. If you use the keyboard click/alt-tab on the corresponding keyboard player instance.

About Codename Cure

Codename Cure is a first person, co-operative zombie game running on the Source Engine. With support for up to five players and providing immersive, fast-paced zombie fragging with fully dynamic and objective based missions. As a team of special military operatives utilising a range of powerful weapons and equipment (assault rifles, shotguns, sentry guns, supply chests and more), players are tasked with curing infected areas of a post-apocalyptic world by planting controlled explosives before pulling a short sharp exit. Cure can be played both on and offline, with or without computer controlled team mates. The game sports a variety of difficulty options which adapt dynamically with the number of players. It includes five balanced player classes: Pointman, Support, Assault, Technician and Sniper.

. . . ``sip`` . . . Hello there fellow nucleus user, It is i "Moss_OH" and i shall teach you how to enjoy this handler along with your friends and family (Especially with your "special" friend) WITH MODS!!!. Similar with the L4D2 method of adding mods to the handler, Copy/move your mods from [workshop\content\355180] into the "custom" folder in [codename: cure/cure/custom] (I recommend naming each mod individually to know which mod does what). And that's pretty much it, Let me know if this method worked for you. Huge shoutout to talos91 for the tip and to birden for making this handler possible. Now if you excuse me i got a wrestling show to catch. ``sip``
