The game is a free-to-play, browser-based iteration of the World War II tank tactics franchise, and includes tank combat, a new card collecting system and both single and multiplayer modes. The trading card system is the series' newest gameplay mechanic — it will allow players to collect and trade miniatures of tanks, infantry and artillery to personalize their army, as well as create a deck of commands that will allow for air strikes.
The first Panzer General game was developed by Strategic Simulations, Inc. and launched for Windows PC in 1994. It has since spawned an entire series about combined-arms tactics in real and fictitious wars. Ubisoft acquired Strategic Simulations, Inc. and the Panzer brand name in 2001. Panzer General Online is the first game in the series to go free-to-play.
