Bionic Commando is just an excellent game. I downloaded this game having only seen the preview video for it and it is fun. It has the old school feel of the original Bionic Commando with the updated graphics of today. Like its old school counterpart It can be challenging. I've played on the normal setting and it has given me a few problems. Most of the problems isn't from the enemies but in the timing of the swings - which is what every level is designed around.
There are a couple of things that get repetitive and I could have done without them. That is the top down view missions. From the main map screen if an enemy vehicle hits your chopper a mission starts from this different view point. At first they are fun but towards the end they are just a nuisance.
Like most platformers timing is crucial. If you have a problem with multiple quick movements you may find yourself dying a lot. Download the demo first for a taste and then if you think you enjoy the mechanics buy the game. It can keep you occupied for longer than a movie for the same or lower price.
