great fun
Nice, addictive, bloody, exciting, but seems to me to be impossible to finish except on practice... There are not nearly enough health packets, in my opinion.
Also, extremely annoying that you can't change weapons. If I decide I want to change tactics, I can't build up a different path but keep my best weapon, I have to use the last weapon I bought even if it is really bad and I have already bought something better. This loses the game a couple of points...
