Snagged the F.E.A.R. bundle, never finished F.3.A.R. on PS3 and F.E.A.R. on 360 was probably the scariest shit i've ever played.

Thanks Basil!

Having a dedicated thread to remind us the numerous deals and giveaways is great. I usually only find out about these deals once they're over, so it will be very useful.

So can we post links to giveaways here? Because I know a ton. Most of these are referral links, I'll try to post if the contest has any regional restrictions.

I recommend the sites SteamGifts and SteamCompanion.
