Zero Point has just released two new co-op missions for Interstellar Marines (which now makes six overall), along with new gameplay mechanics (improved unscripted AI and suppressed weapons) that allow for stealth.
"Our community members love the co-op maps we've already introduced, and we want to give them even more of the same," said Kim Haar Jørgensen of the new maps, before explaining the introduction of the stealth: "We want to encourage players to use even more tactical gameplay, and these new features give players the ability to slip past their enemies using stealth, rather than simply going in guns blazing."
We played the Early Access game during a recent livestream, which you can see below.
