This is the perfected version of Men of War and although very similar to Assault Squad 1, is now the only way to play online since gamespy died.
The game is more balanced than other and the special points/units make for some fun turnaround points in online games.
Recently there were some major updates which bugged the hell out of the game and killed the playerbase as it became almost unplayable online. Thankfully they have been sending out weekly patches, sometimes twice a week for the last month and it is now stable again.
Only two things I will warn you about:
1) if you are new to the game, expect to be chewed up unless against other newbies.......very steep learning curve
2) it really does help to either have some historical knowledge of the ww2 units and their effectiveness or a friend that can brief/run you through faction units so you know what works against what.....saves you a lot trial and error
but most of all...its countless fun and no two games will ever be the same because of the variety of units and players. Between this game and the original men of war, I have about 1500games and I still keep coming back daily after years and years. Cant recommend enough!
