Free FPS games

[Dualpancakes]

I have the motorola droid 3 and don't really like the casual games that most people play on phones. I was wondering does anyone know about good fps games that are free (I don't know how to buy things on the android marketplace)

Its not free... but Sandstorm HD by Gameloft is a good game. You need to setup a credit card to buy anything in the Android Market.
