This game always felt like a work-in-progress than an actual release. With the sub par graphics and difficult playability, this seemed like a conversion done on the cheap and rushed out. One of the biggest annoyances is that you can't move and use your weapon at the same time. The blocky characters and simple background didn't do much in adding to the realism.
I'm assuming this game was done by some European company. With them, it was hit-or-miss. Sometimes you got something with brilliant graphics, sound, and play. Other times you had something like this!
