I loved the PS2 game.
It is one of my favorite PS2 games. Gave me good practice at getting used to moving and shifting sight with two joysticks. Made me pick up my armor core game and continue playing it because I wanted more transformers-like action.
I thought the game difficulty was actually pretty good for me. I mean it was tough enough that I just just crush the game the first time through. I had to stop and think about what I was doing, else I lost. But there wasn't any fustratingly unbeatable parts either. Then on Commander mode, it increased the difficulty enough to completely change the way I played the game.
The first time I played it through, I pretty much just used Red Alert the entire time, Prime for the bosses, and hot shot only when retrieving mini-cons.
And the first time against Tidal Wave, I used the missle shield & buildup, (making me near invincible) and stood on the first island, looking straight up and firing my sniper rifle at the guy's head, piece of cake
Then in commander mode, I didn't use red alert at all. Mainly I used hotshot. Since I knew exactly where to go and how to get the mini-cons, I just raced past enemies, left and right. The speed booster became my best friend.
In commander mode vs Tidal Wave, I had a tough time, but figured out a way to get him. I had the sniper rifle, speed boast, and the extra range with prime. I just went to the middle of the pool of water, where Tidal wave couldn't reach me with his missles or lasers. When he was finished firing, I'd walk slightly into range, fire at him, then boost away when his missles came near me.
The toughest part was killing all those flying guys he released.
Later in the last stage, I had a tough time beating this one bunker. The one with no objects and 4 groups of 3 medium drones with shields and a swordguy. Nowhere to hide and not enough fire power to kill them faster then me dieing.
That is until I crushed them using the Vortex mini-con, you know, the near useless one that whips out a tornado that throws the guys into the air doing moderate damage with a long recharge time. In the bunkers, they make the guys hit the ceilings and take more damage.
