I found the tank sections most challenging during my Insane Difficulty run. The Stasis disc mods made the rest pretty manageable.
Agreed. The tank and light cycle sections were the only parts of the game I had difficulty with.
With the Stasis "stealth" mod though, the rest of the game was "easy mode" to me.
I have it for XBOX360, and I think that only ones I need are the 100 light cycle derez's and the online achievements.
I'm currently playing thru the game again but this time on PC. I'm currently on the last Chapter on normal mode. I'm going to be playing on Hard next to unlock Insane difficulty and then beat Insane difficulty.
I imagine when I'm done I'll end up having the exact same achievements for both the 360 and the PC! LOL
