In Marine: Alien Invasion you assume the role of the commander of the security forces on the military science vessel "Osiris". After the interrupted space jump weird things start to happen. People are lost, strange shapes are being reported lurking in the corridors. It is your duty to investigate what's happening and defend the ship against deadly alien plague. Marine: Alien Invasion is a Sci-Fi themed tower defense game coming to android and windows phone this year.
During the prison break levels (levels where you have to break through the prison area to free the experimental soldiers) you have to avoid the security system traps. They will kill you instantly on touch.
