I hate those Overlords and their Tri-Beam Lasers, they do more damage than seemingly ANY other enemy in the game, even when I am at level 30 with all the great perks and 9 or above in every S.P.E.C.I.A.L. category, and 85 or above on all skills.
Unfortunately I have already done basically everything in Point Lookout, along with a few other things I missed from the regular game (like the Keller family tapes that lead to the MIRV launcher, the most unnecessary weapon in the game).
I thought it was cool that one of the PL quests has you going to the infamous Dunwich building, not going to go farther than that as far as spoilers...
Now I have to wait a month for Mothership Zeta...
