Get your helmet on
The game has a Halo feel, definitely. The boss battles are easy but somewhat annoying. I found them repiitive and drawn out. The challenges felt real time in the way that they spanned large areas to find where you had to be to reach your goal. This is good. Lots of surprises around corners. There were plenty of different types of enemies in strength. Thats all for now. So I say this game is a definite. If you have not bought it by now and want to rent it. plan on a double rental time, it gives you a good many hours.
The first Resistance, Fall of Man was good also, so if you want a grand old time, buy both and play them both through for a long time of just out right fun.
