Wow, this is an amazing bundle for $10! You get the following:
Deus Ex: Human Revolution - Augmented Edition
Deus Ex: Human Revolution - The Missing Link DLC
Hitman: Blood Money
Just Cause 2
Supreme Commander 2
The Last Remnant
All games activate on Steam. The current retail price on Steam of the games in this pack totals $125. Are they worth that? No, most of them have been on sale for far less in the past. Still, this deal is an exceptional value.
And if you already own some of these games, you'll be happy to know that Amazon gives you individual Steam keys for each one. So, you can gift the games you already own to someone else (unlike when Steam does these bundles).
