This is an interesting game which I don't think I've seen repeated anywhere else. Basically a game wherein you play either as a foot soldier, or as a pilot of several stories-tall mecha. As a mecha you'll fight other mecha as well as enemy soldiers while out of your mech you'll fight other soldiers, but sometimes mecha as well. And the combat is pretty unforgiving. You can be at full health, and die in an instant because some of the guns are that powerful.
So is it a good game? I enjoyed it.
The combat is varied with the two modes. They're both point and shoot but the soldier and mecha weapons are quite distinct. The graphics are a little dated of course, the story is a bit hammy, and the action is a little unrealistic style wise but as a whole it works. It's basically an anime game, as much as Oni was from Bungie, and like Oni this game is fairly good.
My only real problem with the game is some parts were ridiculously difficult. There's one part where you have to fight some rogue pilot on top of a platform near a helijet and the enemy guy has some ridiculously proportioned gun that can blow you apart in two shots. I tried about a dozen times but couldn't even get close to the guy. Eventually, he either got stuck on terrain or died somehow that wasn't by doing. Basically the game screwed up and I benefitted from it. Later on you fight a mecha while on foot. Man vs Mecha is a bad idea, for the man that is. Like any mecha you really need a platoon of guys to take it down, one on one is more like suicide and the game reflects this as the battle is quite difficult.
As is the entire final arc. Though like most games, the final boss battle is ridiculously easy compared to what you have to do to get there.
So all in all. Some balance issues I would say.
But still a fun game and worth a go. It's not perfect, but for anime-mecha combat there's not much else on the market and it's unique from my experience.
