I didn't get to much DLC stuff on my first and only previous playthrough, so I am getting to all of it now.

At Point Lookout I received the Tribal quest to get the Punga seeds.

Those hallucination effects were something I was not expecting!

Especially since I had just been playing Sad Satan. Creepy effing game.

Later when going through Calvert's bunker, the visual psychological effects reminded me of S.T.A.L.K.E.R.

Anybody play that game too?

yep. i agree the point lookout hallucinations were kinda strange, didn't expect that in the game especially in that DLC. But was a fun experience.
