The voice acting and graphics aren't great..but the action can get good at times.
There was this one instance when i was searching around through the scope of that supergun, and spotted a group bugs/parasites. I zoomed in on the group and fired. I killed one & the rest scattered like roaches. One of them climbed up the wall and started heading toward me..little suckers are quick too.
The thing got fairly close bfore i hit it with a shotgun blast.
