Men of War: Assault Squad 2, FREE on Steam this weekend.
Latest title in the long running series. Perfect time to give it a try I guess. I've been hooked since Soldiers Heroes of WW2 and got into modding through one of the games in the series (Faces of War) and even worked on one of the titles. (few years back).
A bit of a warning, very, very steep learning curve. You can expect to be blown to bits… a lot… until you get a hang of it :)
Have fun.
Quite a good game if you are in to your RTS games that require a ton of micro.
