For a while now ive been looking to play an old game that was made probably back in 2013. It was a sci-fi game, and the directive was to build around this sphere thing to protect it and cub monsters would try to climb, blow up, and fly into your surrounding wall to get across it to destroy the sphere. Trust me, it is an oldy but if anyone here can find that game, id be grateful. I can remember that you had a sword, but as you got more kills and leveled up you gould use a bow, then crossbow. (and I think mabye a staff that had a blue orb on it) the player characters looked like guards. Im now starting to think that giving more information might lead to overcomplicating things.
