I've read comments that the suit systems are less interesting and more automated than in the first game. For example, not only do you automatically acivate the suit's speed system when you run, but you can't run WITHOUT the suit automatically activating, and that running with the suit enhancement isn't particularly fast to begin with now.
What's your take?
Maximum Speed in C1 was pointless to begin with.
I found it great in Warhead. I don't know if that's because of something special about Warhead or because by Warhead I was tired of trying to stealth.
You use it for hit and run. Come at guys in stealth, shoot the crap out of them, switch to speed and run away. Wait for regen, repeat.
