Great Idea, not very good excecution.
But I couldn't help myself, it's Iron Man for God's sake!! I had to buy it!! The game started out very promising. Playing as the "cave-created" Iron Man suit was interesting. Only having the flame thrower and some missles made for a different fighting style than you would use for the rest of the game. You really got a chance to use some of the melee stragety here. I will admit that the enemies are not very smart. However, I've seen dumber enemies (you may recall Star Wars Battlefront II where an enemy would get stuck in a corner and keep bumping into the walls). At least these enemies show some gumption and keep tracking you down. The tanks even drive off road to try and get to you.
When level 2 begins and you can fly, that's when the game gets really fun. Flying towards an enemy and blasting them with your repulsars is probably the most fun I've had playing a video game in a long time. After spending MANY hours playing Iron Man in Marvel's Ultimate Alliance, it's great to let Iron Man loose in an open arena.
As many reviewers have probably mentioned, the levels themselves are not very complicated, except for the vast amount of enemies. The worst being the constantly replenished jets flying overhead bombarding you with missle after missle. Not to mention the ground troop attacks. There's a reason why you are taught to dodge during your training mission (Level 2) and I recomend using the chaff or shield. That's what's nice about this game, "What works on one level may not work as well on another." That statement was taken from the Marvel interview with Andy Alamano, producer of the Iron Man game.
You can take from this game what you want. It's not the worst movie tie-in game ever made by a long shot. But there was room for improvements as well (check points throughout the missions for instance). But once you have your skills down, this makes for one Hell of a ride.
