Freeware Gaming

First up we have War Gears Crossing the Redzone which excels at explosions and decent graphics. It's currently in beta but plays great.
Next up we have Beautiful Escape: The Dungeoneer which is like a game-based Hostel/Saw torture porn adventure. I'm not a big fan of either movie series or torture porn for that matter, but the game is an interesting experience. A review can be found here which explains my feelings on the game verbatim.
