I had fun playing this. The gameplay is good and fast paced. It is not often I that I recnognize good gameplay, but here it is. Finished Jack Hammer in one sitting.

Some levels suffer from inescapable traps where suicide or grenade jumping are the only ways out (beta symptoms?). It may annoy the more sensitive player.

The visuals of jack hammer is more akin to oldschool marathon mapping. Which is more or less good depending on your taste.

I gave this scenario a 3. It's a good ride with some bumps.
