MW2 on veteran, like a boss.
If you dont count being shit to the ground then be revived on OP:FP DR then that aswell, but only on the easiest difficulty.
Hell no, they were both challenging games, i remember sitting on hornets nest for 30 mins in one spot waiting for all enemies to need to reload at the same time so i could pop off a shot or two at one of them just so i woulnt die. And DR was a very nice game to play without death, at times it was bordering close to impossible, but its doable aslong as you have basic military tactics in mind.
