Game Space Big Gun

Space work is really a challenge for me, only complete the work outplace is not enough, it's a rather a tough road on your way back, now you are 20000000000 miles away from the earth, you need to fight the monster aliens on the way and get back, move and shoot the monsters down, try to avoid the builts from your enemies since it will cause your life, collect items to upgrade your ability, but if you die for once, you need to do it again. Good luck and have fun!
