I checked out hell let loose. AT first sight it looks good. But the same gameplay gets old quick. Now that could be said for a lot of games. Playing Arma with Pigs On The Wing is always exciting. One week we are the Russians fighting the Germans in WW2, the next week are fighting the chinese on Tanoa, the next week we are in Vietnam dropping napalm, or fighting the russians as the USA in the mid 80's to fighting the Jihaddists in the desert.
The MODS created for Arma are just plain crazy. From crazy explosions to the holy hand grenade of Antioch.
I have yet to try out the new Post Scriptum update as I have heard they made the Sherman tank have a fully functioning transmission and its able to withstand several hits from german tanks.
