It's okay, but...
It really needs a sensitivity slider in the options menu to fine tune the mouse movement. It is almost unplayable using a third party Logitech optical mouse. I even lowered my sensitivity down all the way at my desktop and it's still way too fast!
Other than that, it's okay. It's kind of like a more glorified tank game by Atari. I think it was named Battlefield. It seems to run okay, but the mouse it so touchy, it is hard to aim. It really needs a sensitivity slider for fine tuning the mouse movement speed.
Nice explosions and neon settings. You can look in all directions, as well as up & down. The pictures didn't seem to show this, but you do have full visual movement. Just another FPS on the flooded shooter market. The only thing it has going for it is the retro neon look and feel. It's worth the small asking price for sure, but ONLY after they add a setting for mouse sensitivity. At this point, it is almost unplayable for me. I will still give it 3 stars for effort.
