These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Time Splitters
Catharsis Factor: Arcade: Amateur League: Nightstick: Damn Cold Out Here. First, fire your flare gun at a snowman. Then listen to the screaming. Repeat.
Crazy Awesome: Monkeys, zombies and giant gingerbread men wielding rocket launchers. And this is just one combination.
This troper found that the main theme splices very well into jazz trombone.
No mention of the Victorian multiplayer tileset music in TS2? Not surprised, sadly. I could only find it in that particular tileset, nowhere else in the game. Which is probably why it's underappreciated.
Actually, the Victorian tileset music is, if I recall correctly, the "Castle" theme from TS1.
Mansion in TimeSplitters: Future Perfect, arguably, was scrappy for three reasons. One, Jo-Beth Casey. Second, Deer Haunter. Third, the last boss of the level. You know which trope he goes under. Oh! Let's not forget that the level was actually pretty scary, to boot.
The Deer Haunter can be easily killed by standing with your back touching the wall of the hole it came out of: it can't get close enough to hit you. And Jo-Beth Casey? Hilarious.
Jo-Beth Casey isn't as funny when a glitch causes her to attack you for no reason...
The Hooded Man in Future Perfect. You have to protect your past self from Time Assassins and TimeSplitters until he gets to the base it doesn't get bad until the Splitters show up though.
Something to Crow About. Powerful enemies who can fill you full of plasma in a few seconds, shielded enemies you have to switch quickly to the Electrotool and back to defeat, flying mechs not unlike the "boss" of U-Genius U-Genix, annoying rolling robots, the stage is long, there are two bosses, and the latter of those two bosses is That One Boss.
Video Game Cruelty Potential: Play a Team Death Match as a robot with nothing but flamethrowers and make sure none of your enemies are robots. Just do it.
You've definitely played on the Siberia stage in FP just to block an AI team's base with the jeep.
