Good game. Takes a little getting used to and can be tough at times. But it is beatable as long as you keep your armour and health up when can. The ending seemed a bit abrupt. But overall not bad. Good graphics and a variety of opponents.
The power ups have a bit too short a life span. Grenade did not seem to work sometimes and ended up never using it.
Some tips. Save your ricochet gun for the bosses. Try to take advantage of the power ups. but learn to not rely on them. Stay mobile especially at the lower levels as one of the rocket drones has seeking shots. Explore, be patient and backtrack to the lift to heal or re-armour as needed.
