So... I've stated playing Armored Core 4 recently, and I have to say, it's one of the best mech games I've played. However, that's not saying much when compared to all the "wonderful" Gundam games. I have to say that I love using the boost almost constantley which gives the game a great feel The only problem is that the levels are so confining, not to mention way to short. Once you actually get into action and you're kicking ass, you finish the mission. Then you're like, "Well... I won... wish I could've kicked more ass... but I did beat it..." Something else to mention is that the game isn't all that difficult. My favorite strategy is to over boost right into their faces and use an energy sword...repeatedly...in the face... Anyways, my violent tendencies aside, I do overall enjoy the game and you can make it harder by doing the hard difficulty which at times seems like too much of a jump.
