Painkiller is an extremely atmospheric FPS, I can really recommend it to anyone considering a purchase.
Speaking of Painkiller... Have our questions really gone forgotten or were there some answers for them which I missed somehow?

Passing. I got R.R. here from GOG already, and am not interested in purchasing the others.
I'd say R.R. and Painkiller are the best of this promo, get these two. ;)

Aquanox was on my wishlist so, no brainer.
Thanks guys!

Aquanox: not a bad underwater shooters. It's really not a FPS, more of a Descent/Terminal Velocity/Fury3+a linear story kind of deal, just...underwater. Back in the day it was at the top of the graphics curve, still looks OK.
Redneck Rampage occupies a spot between the horrible Witchhaven/TEKWar Build engine games and the "real" Build Engine games (Blood, Duke3D). One-joke pony with terrible, flat levels and sloppy gameplay. Great soundtrack, though. The whole "cuss" thing seems so quaint, now.
Postal 2 is in no way a good shooter and is amateurish on every level. For some reason, however (probably bullied too much as a kid), I like it.
Painkiller is the last decade's best pure shooter. No levelling, no story, just frenetic, well-balanced, exhilarating FPS action.

I look at the prices for the games and they still say the original prices. Does the discount get taken off once the purchase actually goes through?

Make sure you are selecting the games from the Promo Page - if you add them to your cart from the game cards directly, the prices won't show up, and I don't believe you'll receive the discount either.

Oh ok there we go that worked. Still very new to how GOG works so I wasn't sure. Thank you!

Thought I would just get Redneck Rampage but ended up with Painkiller as well. Can't wait to play them! Been itching for some FPS lately.

Actually the discount should show in payment page (after you click "proceed to payment", the screen where you choose payment medhod and write credit card info) even when you select games from catalog. Unfortunately the game catalog prices are never updated to reflect promotions and GOG should rectify this at some point to avoid confusion.

Bought Redneck Rampage and Painkiller.
Thanks for the recomendations!

Just bought Postal 2, might buy another one of the games later today.

After a long run of passing on the promos I was sucked in by Painkiller and Aquanox this weekend. I played quite a lot of painkiller a few years back but never finished it, a very enjoyable game and with the expansions it was a no brainer.
Aquanox has been tempting me for a while now, I know it might not be the best of games but the setting really intrigues me and the graphics look pretty good too.

Postal & Painkiller are my. THX

I clicked on the ad for all 4 shooters and it added the total for them up all together. Came out to 19 dollars or something. I just went ahead and got all four of them. :P Great deal. ESPECIALLY when I'd normally pay that price for just Postal 2 and Painkiller.
Great deal on that one GOG. :D
