i have been rampage inside Institute few times before for fun, but I have never seen so many of them spawned at underground O_O. is this a bug? there are enough synths to level me up from lvl55 to lvl60 (tried to clear them few times, psycho jet, med-x, and spam all chem with shotgun, plasma rifle...etc none works. just too many of them at the end i used missle launcher shoot the room and the explosion kill everything in the room lol

When in doubt use a missile launcher uhh?

yep, my official of weapon of mass destruction. much more reliable than mini nukes. u can shoot very far. make it auto track targeting. and good blast range. perfect weapon of choice for your daily assassination

Something I never thought I'd see in a AT-4 manual:

"Always remember when utilizing the AT-4 shoulder fired missile launcher during CQB actions to make sure the operator isn't standing in the same enclosure as the detonation of the warhead is set to occur. Be warned that the structural integrity of most buildings will be severely compromised during such actions unless sufficiently hardened, like bunkers, underground parking garages and soviet era apartment housing. Also make sure the operator leaves enough space to the rear for back blast to avert catastrophic consequences."
