Blitz 1941 is a 2D historical tank battle sim MMO based upon real conflict between Germany and the Soviet Union during World War II. The game features over 60 real tanks to choose from to do battle in 15 Soviet cities, each a strategic point based on its real-life counterpart. Players may choose sides, pick the tank they want (as each side's assortment varies) and customize his or her experience. Enhancing the gameplay is the ability to travel from one city to the next to fight in a siege for occupation. The winning side gains strategic advantages such as supplies and economic might. Other PvP options include one on one fights or simultaneous 200 player combat. Tank armor and other aspects can be customized, and there is a player economy for trades.

Blitz 1941 is free to download and play. It is supported by an item shop, where upgrades may be purchased.
