Will repeat it here:
For those who want to take advantage of the GamersGate sale but don't want to keep track of another account:
Saints Row 2 and UT3 activate on Steam
Red Faction: Guerilla activates on Impulse.

It's too bad Red Faction Guerilla is around 13 USD for europeans.

Gish pay what you want forever, and they added lots of 3rd party levels as well.

A few more games have been added to Gamersgate's sales.

Good point.
Ya, they at least put it in BOLD RED letters at the top of the game description:
"Won't work with any Borderlands DLC!!!"
I got bit by that myself 'cause I got my copy of Borderlands off of D2D so I could not take advantage of the Steam deals for the DLC awhile back (they were like 3 bucks a piece!; normally 10). At least I can still get the DLC from D2D if I wish... and only like 1 of them is worth it (from what I've read of reviews ;) ).

Nation Red is 50% off on Steam. Anyone know this game? It's another survival horror game but it is any good?

It's not really a survival horror, more of a top-down shooter. Closer to Smash TV than Resident Evil. It's decent, but I didn't really enjoy it. There's a demo, but be aware that they have added much more content since it came out.

I played the demo and there's no scenery whatsoever. It's just you and some zombies on this completely bland scrap of land. Gets boring fast.

Good if you like the genre and the developers recently added co-op.

I APPROVE.

I used to really enjoy it when it first came out, but they've changed it so much that it's no longer really the same game and I no longer find it fun.

It is $29.99 USD on Steam too since 2 or 3 weeks. Also you can add your game to EA Downloader and get EA version and can play without the Steam too.

Yay for nonsensical regional restrictions!

It's not restricted, you just have to look for the UK version:
