nice concept not the regular zombie shooter base building and raids are nice no movement control you just aim and shoot you can still advance in the game without paying money but becomes too slow after a while like region 4 or 5 but the main issue is the slow loading between screens feels too heavy (processing power) and too much data for a game that shouldn't be too demanding i've played bigger and better games in term of graphics and complexity and felt faster than this one, whenever you press on something any icon or menu or loading a mission takes a very long time.
