For a chaotic, mutant-filled shooter experience, nothing’s more straightforward than to play with Friends in Guntouchables. The best part is Guntouchables doesn’t bury multiplayer behind a mess of menus or force you to add people as in-game friends. It uses a simple code-based lobby system that works in a few quick steps.
While you can jump in solo, the real fun kicks in when you’re side by side with friends. The game’s an online co-op doomsday roguelite for up to four characters, where you and your crew of heavily armed “preppers” take on endless waves of evolving mutants.
Guntouchables – How to play with Friends

To get things rolling, fire up Guntouchables and head into the multiplayer section. You’ll see a list of public lobbies based on your region, but skip joining any of them if you’re setting up for friends. Instead, look to the bottom-right corner and hit the option to create your own lobby. As soon as it’s up, the game will give you a unique code.
Before you do anything else, switch your lobby from public to private; this keeps random players from sliding in. Now you’ve got your code locked down, share it directly with your friends.
On their end, it’s just as simple. They launch the game, head into multiplayer, and spot the “Join via code” option in the top-right corner. Once they punch in the code you gave them, they’ll drop straight into your lobby. No long invites, no server shuffling, you just instant connection. After everyone’s in, pick your game mode and hit start.
At first, a lot of the modes will be locked, but you’ll unlock them naturally just by playing. The good thing is you’re not locked into co-op forever if you ever want a breather from your squad and test yourself against the chaos solo, the single-player has enough bite to keep things intense. So you can focus on building stamina while you unlock everything.
Guntouchables keeps the process lean so you can focus on the fun. So you just need to load up, link up, and taking the fight to the mutants without wasting time in menus.
