The mech fight wasn't nearly as bad as I'd expected it to be. I had more than enough health to get through it without dying, despite the fact that you can't dodge at all. So, pretty much the only viable strategy is to have your mech walk around in circles to keep you from getting bored, while holding down the chain gun, and hammering on the grenades/missiles. I tried moving in and out from behind pillars/walls to avoid damage, but it doesn't really work consistently as the mech gets it feet tangled up if you try to shift directions back and forth too quickly.
Anywho, I finished the game. The final boss was really screwed up, and basically required you to shoot a tiny little dot on it's body to kill it. Although, considering I couldn't see the damn thing because it was so tiny, I basically had to guess, which took forever and wasted a lot of ammo and time. Eventually it died, and there was like no plot aftewards, so the entire storyline was pointless. I thought it might actually tie into the second game somehow, but that wasn't the case.
Oh well... At least I know better not to play this game again.
