Invasion 1944 is a historically accurate World War Two total conversion mod for ARMA 2: Combined Operations(ARMA2 + Arrowhead) centering on the European theater.
Here's a peak at a big surprise for 2.6, another new map! Winter Merderet is a new map based on a design worked up by an old member NSU, and heavily updated by Macolik. The map is inspired by the areas around the Merderet river but is a fictional map which allowed us greater freedom in designing an interesting play area that feels very different to Omaha. The map is designed primarily for TvT gameplay especially for tanks with lots of open areas, as well as a dense destroyed town in the center of map around a bridge crossing.
this makes me want to buy ARM2 even more!
I would HIGHLY suggest that you get the entire ARMA II series. ACE, ACRE, PR ARMA II and this mod are the best reasons why to get it.
