"Marauder," a game currently in development by a small UK studio, places players in the role of a space pirate in an alternate universe after World War II where humanity chose to travel to space using Sherman tanks.
You can either join a team of space pirates in "Marauder" or you can go it alone in an area full of abandoned spacecraft and asteroid mining stations. You will board the ship, take whatever isn't secured down, and then flee as fast as you can. You may run into computer-controlled NPC foes, or fully-equipped players looking for the same riches. Escape from Tarkov is a similar game.
