This week's Humble Weekly Sale is pretty cool for one reason
https://www.humblebundle.com/weekly
Can you guess the reason?
$1 tier
ARMA II - http://store.steampo....com/app/33900/ - $12.99
Take on Helicopters - http://store.steampo....com/app/65730/ - $19.99
UFO: Afterlight - http://store.steampo...com/app/237950/ - $6.99
Alpha Prime - http://store.steampo...d.com/app/2590/ - $4.99
ARMA Gold Edition - http://store.steampo....com/app/65780/ - $9.99
ARMA Tactics - http://store.steampo...com/app/224860/ - $8.99
$6 tier
Carrier Command: Gaea Mission - http://store.steampo....com/app/65740/ - $32.99
ARMA II: Operation Arrowhead - http://store.steampo....com/app/33930/ - $19.99
ARMA II: DayZ Mod - http://store.steampo...com/app/224580/ - Free, but you need Arrowhead and ARMA II (which are in the bundle) to play
All in total, you get $63.94 worth of games in the 1$ tier, and $116.92 worth in the $6 tier. Plus, you get the free DayZ Mod, which while less impressive than the DayZ Standalone, is a suitable game on its own.
I purchased the $6 tier myself. It's one of the last purchases I can make for a while with my limited gaming budget, but I think it's well worth it.
