if you want to play minecraft but with future stuff like jetpacks similar to the tekkit mod then download XENOMINER. although a indie game on the xbox game store it is addicting!!!!! From giant doors to a complicated crafting system this game is great.although it does have its flaws like the fact that it takes so much time to be able to craft most items. but unlike its other voxel game cousins when you play xenominer you dont have five billion maps by the second day you play nope in xenominer youll spend days or even weeks trying to get a map to a satisfying stage. i encourage you to try it and now thanks to the new update it has multiplayer and we are expecting more additions such as A.I. units such as aliens.   PS: special thanks to gristmill studios for this game. :D
