A playable demo of Gunslugs 2 for PC,Mac and Linux: www.gunslugs.com
There are still some rough edges in the game, but it should give a great indication on what the game will eventually be. The demo takes you through the opening scene, first world, end boss and includes the train crash, so it's a nice little slice of Gunslugs 2 action.
