If you could have only one thing in Game that you could do in Real Life what would it be?
For me, it would be the ability to use satachel charges with just the right mix of explosives. To knock down a few metre across wall, but not the whole building.
Dang it, I could see launching CS into the Island Estate to induce fear, panic, and confusion. Then blasting into the court yard and driving up to the balcony and flashbanging in and out with the hostages in like 2-3 minutes for snails pace (as far as RvS is concerned). And mop the area up with bangs & frags. Now that would be fun
