Threw a grenade out a window, only, I didn't. Now this wasn't your typical 'oh damnit hit the wall self-grenade kill' type deal oh no. Thing went build-a-better-mouse-trap on me.
It bounced off the wall, went out a different window, hit a lamp post (apparently) and sat next to an explosive environmental object. In my panic of initially hitting the wall and not waiting to find out what will happen in a room with a live grenade rolling around, I booked it downstairs and outside. I was taking some bullet fire so I ducked down behind a car to fire back. The grenade went off a while ago (by this point) and lit some barrels on fire. When those finally blew up, they set the car I ducked under on fire. After I'd cleared out the sidestreet the car blew up. I skipped the killcam but two of my teammates saw what happend and where nice enough to relay the events back to me.
Thanks guys! Don't tell me to move or anything.
