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: Vanquish
Big Lipped Alligator Moment: During the Mobile Castle Infiltration Sequence, right before blowing it up, you find a small group of the robots dancing to a beatbox that is actually one of the Mobile Cover Robots. Before you have enough time to think about the robots you just killed, an Unknown shows up, and afterwards you go on to destroying the giant warhammer. Now this is a game that boarderlines science fiction and steampunk fantasy, but Russian Robots doing the Robot to American Music? COME ON.
Heck, the UNKNOWN in general. I mean, what was up with those? A heap of scrap armed with machineguns, with a glowing red core that grows legs and runs away sometimes? That's just weird.
Crazy Awesome: Hold down LB (360) or L2 (PS3). Yeah. That just happened.
Demonic Spider: The Romanovs. If you didn't hate these guys at first, Platinum made damn sure you were gonna hate them sooner or later. There are four different versions of these bastards.
The Romanov F has a flamethrower that will overheat your AR gauge (Where your Crazy Awesome powers come from in the first place). After that, he proceeds to smash you with his club. I bet you're thinking: "Oh I'll just go in critical mode and gain my health back". It's too he overheated your AR Gauge. Which pretty much makes his club a One hit kill attack.
The Romanov G is probably the most dangerous one. He tends to stay far back and tosses missiles at you. Every once in a while he uses the Big One. This missile is a One-Hit Kill and it tracks you. Good thing there's a siren to warn you that it's up close right? Too bad you'll be distracted by other enemies and by the time you hear it, your pretty much fucked. You can't even get up close to this Romanov. If you do, he turns you into Swiss cheese with his Gatling guns.
It's Short, so It Sucks : An average player can possibly get 3-4 hours out the campaign on the normal difficulty, so this came up a bit for some people.
High Octane Nightmare Fuel: When the microwave weapon is fired on San Fransisco, we get a graphic view of its effects, complete with full-body burns, boiling water, and exploding bodies.
Some of Sam's death animations, especially when killed by the Romanovs, are quite squick-worthy. There's the drill-equipped one, which grabs Sam, crushes him, and then slams his body into the ground and drills down through his chest and stomach....
Moral Event Horizon: The Russians go screaming across it in the game's opening scene when they fire the microwave weapon on San Fransisco.
Most Annoying Sound: You'll get real tired of the ARS's cooldown cycle damn fast, especially when you have hundreds of bullets and rockets flying by you.
That One Boss: On God Hard difficulty, Bogeys Alpha and Beta are nightmarishly difficult, and liable to induce a Rage Quit in all but the most insanely determined of gamers. According to the Xbox 360 leaderboards, less than 100 players in the world have actually beaten them on that difficulty setting.
