The Square Enix Humble Bundle is a sequence of unmitigated delight (except for Daikatana and Kane & Lynch 2: Dog Days).
The bundle includes a stellar line up of great games, mostly from the Eidos contingent. The base pay-what-you-want bundle includes the original Thief Gold, the incredible and under-appreciated Anachronox, Mini Ninjas, Hitman: Codename 47, Hitman 2: Silent Assassin and *cough* Daikatana.
Cough up higher than average ($7.38 at time of writing) to receive Deus Ex: Invisible War, Deus Ex: The Fall, Hitman: Absolution, Nosgoth Veteran Pack, Battlestations: Midway and more games to be revealed soon.
Go whole hog and fork out a ridiculous thrifty $15 to also score Deus Ex: Human Revolution Director's Cut, Just Cause 2, Lara Croft and the Guardian of Light, Deus Ex: Game of the Year Edition, and *cough* Kane & Lynch 2: Dog Days.
As usual, you choose how the proceeds are split between publisher, organisers and charity; this time, you'll be benefitting GamesAid and Make-A-Wish.
Unfortunately, it's all PC exclusive this time so Mac and Linux users are out of luck. Note that all products redeem on Steam.
