If you've missed out on Red Faction's latest entry or Darksiders II, this week's Humble Weekly Sale is for you. Pay any amount to get Red Faction: Armageddon, Supreme Commander, SC: Forged Alliance, The Guild 2, and the Neighbours From Hell Compilation. $1 or more gets you Steam keys for everything but the MFH Compilation. Paying $6 or more gets you those games plus Painkiller: Hell and Damnation, ArcaniA, Darksiders II, and Spellforce 2: Faith in Destiny. Everything in that tier unlocks on Steam, and as with every Humble sale, you can donate some or all of your money to either Child's Play or the American Red Cross.
