Mars or Die! is a Nintendo Switch action game developed by 34BigThings. The game revolves around a team of explorers who are tasked with scouting the Martian soil, fighting the disgusting Martian natives, and building defensible outposts to spearhead their inevitable conquest. The player has the honor of commanding the team, surviving, gathering, and building their way to victory.

In Mars or Die!, the player commands two characters: Scout B. Bean and Major B. Bob. Scout Bean is equipped with a personal energy repulsion shield, capable of deflecting devastating blows, while Major Bob is an implacable marksman with a fervent passion for the cause, chocolate, and ballet. The game features base building, including automatic extractors, O2 generators, armories, single-barrel and double-barrel automatic defense turrets, and the most important of them all, a glorious flag! The game's campaign is divided into nine missions, which will be swift, sure, and certain, but in case the Martians put up a fight due to their sheer numbers, players can also entrench and endure an endless warfare.
