This is Scrap Galaxy, made by our good friends over at Catalope Games.
This intense space shooter will be out on Steam December 1, so better add it to your wishlist in time for Christmas! :D
Scrap Galaxy is a local build-and-destroy game for up to 4 players, as seen in the trailer. You build your ship and try to blow your enemies away. Watch out for those pesky mines! They will ruin your day!
