Has potential for good game
It was entertaining 2 hours which it took to finish the game. However, in the end it repeated itself because the plan for clearing each room was the same: run circles around the baddies or just rush them and collect armor and ammo while they die.
Money lost its meaning and was limited only at the very beginning.
Weapons were cool and really ballsy, especially photon weapons.
Photon scatter was overpowered.
The moment the zombies started shooting they stopped being zombies. Instead of big rooms I suggest hallways and small rooms with monsters coming from everywhere so that the player needs to fight for his life and living area.
