This is a new game available on steam for free. You can find the game on steam simply by searching for it. It is a free to play game.
The game basically allows you to battle from 2 different perspective, one as the hero on the battlefield fighting and dying to capture territory. The other is being the general commanding where to send the heroes to fight. More of a tactical side of things.
Playing as a hero you can pick from a few different classes: Infantry, Tank Crewman, Pilot, Paratrooper, or Recon.
The infantry is the 1st and most basic class you can pick, until you rank up you will be stuck with just infantry. Also each soldier you create will need to be ranked up to allow you to change that soldier's class. Infantry gives you access to all weapons that can infantry use including vehicles.
The other classes are also pretty self explainable. What I really want to say about this game is something many games don't have is the concept of limited supplies in the battles and the war overall.
This game is fought battle after battle to win the war. The war is between Germany and America. Each side has units that are called assault units that have a set amount of lives that can be used in battle. The type of unit it is picked by the general and sent into battle by the general as well. These units are than used in battle to try to capture or defend towns from the enemy. So therefore in a battle one side could have planes and the other side could not have any at all. Or in the middle of the battle the planes could arrive and than be used in the battle. These are just 2 of many different things that could happen in battle. It's all part of the bigger picture of winning the war. Units can be reenforced after a battle using funds the general has if the general wants to do that.
This game is still in beta, it has many other features they plan to add to the game. With all this being said it is worth taking a look at and giving it a try. It's free.
