dude, what? Time Splitters 2 is an amazing game. Haven't played it in a while, so I can't really comment on the controls being 'floaty' but I remember them being really tight and refined. Besides sniping, of course, which was nearly impossible (much easier in Future Perfect). But I had more fun with that game then almost any other game that came out around that time.
It's been a while for me too so yeah kind of hard for me to describe. Plus their where a bunch of little things the irked me about the game that on their own wouldn't normally bother me but when put all together ruined the game for me:
-You can't jump
-You are right, sniping IS near impossible and I like to snipe
-heck, I had trouble hitting anything... its just that the problem was just made worse for when you went into the zoom mode of any of the weapons.
-graphics aren't very good, and the style was too cartoony for me. Faces were ugly.
-lazy animation, weak sound effects, severely bland textures
-the monkey was broken in MP, and I fucking refuse to accept a match with anyone who uses the monkey.
-MP stats in general seemed dumb.
-health bar location... WTF is that shit? hard to tell exactly how much health I have (fuzzieness) and it disappears so if I didn't catch it, I don't realize that I need a health pack.
-I read about a map maker in the game and was SORELY disappointed.
-Weapons didn't seem balanced which normally wouldn't be a problem if you just always started with a good one but otherwise you had to spend most of the match trying to find a weapon worth using.
-Story was not very interesting, tad to much cheese.
-missions were varied and unique but hair-pullingly controller-throwingly difficult.
-objectives had a tendency to be way too vague. found myself wondering around trying to figure WTF I was supposed to be doing.
-lowering the difficulty only made the missions shorter, as in, there were gaping chunks of the mission that you couldn't even do unless you played max difficulty.
-bunch of other stuff I can't remember ATM.
The one thing I liked doing was unlocking all the characters with the challenge modes. Those were ok. They were also frustrating though. And the multiplayer map design seemed pretty good. As well as general variety. Which I always appreciate. But the underlying gameplay felt bland and the controls really irked me.
