ARMA for me is about murdering my PC with huge wars and scripting stuff so it looks like a war movie. Sometimes playing with friends, though only if there's like organized scenario. Random ones are meh.
Also screwing around with Wh40k mods and laughing at the puny T-90s and M1s trying to do anything to my huge driving fortress that's spewing fire everywhere around.
EET EESS TEEEH BEEEIINBLEEEIDD!
I JUST CHOKED
THERE'S A FUCKING WH40K MOD FOR ARMA 2!?
Apparently. I recently came across footage of a Baneblade versus dozens of AI tanks. It's ridiculous; a Baneblade is, as Kot stated, supposed to be basically a fortress on treads. It's big and heavy and loaded with guns, including a main battle cannon that fires massive shells.
NOT IN ARMA2. In ArmA2, a Baneblade can turn on a dime while outracing lighter vehicles, flinging them into the air on collision, with a main gun that acts more like a machine gun than a big-ass cannon. I couldn't get past more than a minute of the footage because of that. About the only thing that matched canon was the tank's nigh-indestructibility.
