Overall it's more of the great Armored Core 3. It's a bit shorter and the missions can be tougher, but I never felt like it was an unfair game. I will say that the amount of double AC ambsuhes is a little high. This game taught me to prioritize the mission objective and start running past enemies for a reason. More of a great thing is great, give it a look once you finish Armored Core 3!
