Just wanted to add my kudos. I'm getting a few freezes, usually when attacking in bullet time, but saving on a regular basis anyway thanks to the upped difficulty.
Had my best ever FO3 firefight yesterday. I normally hit the Elementary School FIRST. Playing as a regulator, I didn't reach the school until two days and three levels later.
Popped in the upper back door, laid down a mine at the first intersection(after getting pwned the first run-through), chucked a grenade to the right where I could hear a nearby raider, then retreated back to the door.
This attracted the attention of every single damn raider in the school...and their little dog, too. With increased spawns. How my level 4 regulator survived, wearing only her regulation(hah) duster, a pre-war hat, and no cover to speak of, I'm not entirely sure. All I know is I was jumping in and out of bullet-time, and trying to score as many head-shots with the assault rifle as I could, using the melee raiders as shields from the gun-toting ones behind.
When I was done, my own heart was as loud as the one coming from the speakers.
And I was level five.
Also, when I finally cleaned up the mess and had a nap to recover my wounds, I made my way to the basemant, where I did my landmine trick again, but this time when I threw the grenade and retreated to the entrance, I waited in vain to pick off those chasing me. There was however, about a minute's worth of crippled limb messages.
I found two dead raiders where I had left the mine, and another three cowering together at the other end of the level. Good times.
And, not sure if its a bug, but I unloaded about 40 rounds from my silenced 10mm pistol into one of the giant worker ants on that level, and I think I missed every time from point blank range. Not sure if this has anything to do with my same problem with this gun and shooting raiders(taking 5+ headshots to kill, repair & small arms 50+). Hunting rifle and assault rifle seem to be more than sufficient, though.
