Steam for Linux Celebration Sale - 50% to 75% Off

Steam is having a huge Sale in Celebration for Steam for Linux. Linux game titles are from 50% all the way up to 80% off. Despite the sale stating it was as high as 75% off, I saw Serious Sam 3 BFE for 80% off, which brings it down to a mere $7.99 which is normally a $39.99 game.

There are now 100 items within Steam's Linux section. I am very excited about this. Here is just some of the games on sale;
Intrusion 2 = 66% off brings it to $3.50
Serious Sam 3 BFE = 80% off brings it to $7.99
4th Year Anniversary World of Goo = 75% off brings it to $2.49
Trine 2 = 75% off brings it to $3.74
Half Life = 75% off brings it to $2.49
Counter Strike Source = 75% off brings it to $4.99
Bastion = 75% off brings it to $3.74
Amnesia = 75% off brings it to $5.00

This is an awesome sale and I picked up Intrusion 2 and Bastion for a mere $7.24. What will you be picking up?
