Duet places you in a scrolling military scenario where you infiltrate enemy territory to retrieve vital documents and return safely. You can fight your way through alone, relying on stealth and agility – or team up in two-player mode as a coordinated commando pair, where cooperation determines survival. Minefields, tanks, and foot patrols turn every advance into a dangerous challenge that demands precise movement and smart tactics. Whether solo or in tandem – only those who stay focused and work strategically will survive this uncompromising mission.
