You drop into the lobby and the mission screen is eerily quiet. I’ve waited with a full squad slot and nothing but crickets over voice chat. You’re one invite away from turning that silence into controlled mayhem.
I’m talking about Deep Rock Galactic: Rogue Core — the roguelite twist on the DRG formula that still plays best with other miners. You can run up to four players in co-op; I’ll walk you through the fastest, least confusing way to get your crew into the same cave, using Steam and a few handy social tools like Discord.
How do I invite friends to Deep Rock Galactic: Rogue Core?
Short answer: use the Mission Terminal in the lobby and choose a friends-only host, or let Steam do the heavy lifting with its Friends List join feature.
I check my Steam friends list like a mechanic checks gauges — names that need attention go to the top.
The lobby is a bustling train station of miners. Go to the Mission Terminal in the lobby area to select or prepare a run: change loadouts, apply enhancements, and pick the mission you want. If you want only your mates, choose Host (Friends Only) from the options. That’s the cleanest way to invite people without strangers filtering in.
- Everyone needs a copy of the game on Steam.
- Finish or skip the tutorial so you can access the Mission Terminal.
- At the Mission Terminal: pick your mission, then select Host (Friends Only).
- Have your friends join from your Steam Friends List or accept an invite you send via Discord or Steam chat.

Can I join a friend’s session from Steam?
Yes. If you’re not already in a mission, friends can click Join Game from the Steam overlay or Friends List and hop straight into your lobby. That works as long as the host hasn’t been sealed into a mission instance that blocks joins.
I’ve jumped into public sessions when my squad was scattered and learned one thing fast — you either mesh or the mission eats you.
If you don’t have friends available, the Mission Terminal also lets you Join public servers created by other players. Pick a server from the list and join their round; the game will match you to runs that other players are hosting. You can also create a public lobby and players will auto-join if they’re queued for the same mission.
- Select Join at the Mission Terminal to browse active rounds.
- Create a public lobby if you want more players; strangers will fill empty slots.
- Keep voice chat like Discord open — coordination beats chaos every time.

How many players can play co-op in Rogue Core?
Up to four players per mission. That four-person ceiling keeps every run intense — your squad will be a pressure cooker of chaos when things go pear-shaped.
I recommend pairing Steam’s Friends List join with a Discord invite link for quick coordination, and using the Mission Terminal settings to control who gets into your lobby. Want to risk a public run or keep it strictly friends-only — which one will cost you fewer body bag spawns?
