Space Repair

You, commander of the space mission ALPHA-11, were woken up by your lieutenant. Your mission base was damaged by some unknown intelligent species. You weren't aware that life exists on this damned place in space. Unfortunately those aliens stole some parts of your ship. Your engineers are working hard to repair the damaged spaceship. To secure your mission and get back to your family alive, you must defend your base against hordes of aliens until your engineers finish their work. Space Repair is a classical tower defense game. Build your turrets to obliterate the upcoming aliens. To increase your resource supply, you can build an iridium drill or a photon cell. Try to lure the aliens through a maze of towers. But be aware that blocking their walking path completely results in a total rampage...
