This week's new additions to the Xbox Live Arcade library are both out of this world and down to earth, as Star Trek D-A-C and Texas Cheat 'Em become Xbox 360 digital downloads on Wednesday.

Both Naked Sky Entertainment's Star Trek D-A-C and Wideload's Texas Cheat 'Em will set Xbox Live subscribers 800 Microsoft Points, offering top-down space combat and rule-bending, card-based mini-games, respectively. Let us know of your intent to pick either up in the comments.
