Accidental Innuendo: Granted, they're robots and so don't really have genitalia (despite having both male and female examples of the species), but when fighting the Destroyers, after you blast the fuel cell in the back of the tank, forcing them to transform, if you keep your targeting reticule on that spot, you find that you're basically shooting them in the ass. Their heavy armor and moving head means that, basically, the best place to shoot them is in the crotch or the ass.
Demonic Spiders: Pretty much literal - there are robot spiders that swarm you. Even worse, in Trypticon's boss battle, he spawns lots of them. Cloakers like working with them in Kaon, and themselves are pretty good examples. When you see the glow of their plasma cannons, you'll probably be spraying bullets like crazy trying to hit its wielder.
Possibly the ultimate examples of Demonic Spiders in the game are otherwise garden-variety mooks equipped with regenerating overshields, a seemingly-infinite supply of grenades, and EMP shotguns. Because of this, they're extremely tough, capable of dealing incredible amounts of damage, and prone to using hit-and-run tactics—and if you don't kill them fast enough, the shields come back up and you have to start all over again. There are times when you need to kill entire waves of these guys, and they're easily some of the most difficult encounters in the game.
Artillery Specialists in the DS version. It's damned near impossible to hit them, and they strike like a runaway train.
Also: Brutes. They can only be damaged from behind, they carry shields to protect themselves from the front, they do a massive amount of damage if they hit you, and most times, they'll chase you rather than your AI-controlled teammates, making it extremely difficult to work your way around behind them to shoot their backpacks.
8.8: Gamespot gave War for Cybertron a 6.5 out of 10 — significantly lower than other review sites, which typically awarded scores in the 7-9 out of 10 range.
Maybe they just played the PC version for their review?
Game Breaker: The Leader-class in multiplayer. They get access to some of the strongest weapons in the game the ability to boost damage and armor through their Warcry ability. Given the Fusion Cannon or Magma Frag Launcher meant they could bring down enemies in a couple hits at most and take way too much damage before dying.
Moral Event Horizon: Megatron using his Kill Sat to destroy the Autobot shuttles fleeing Cybertron after the planet shuts down because he's pissed at Optimus for "defying him."
Most Annoying Sound: Not at first, but wait till you have to fight Trypticon multiple times (and you will). You will sicken of hearing "You thought you could destroy me?! You thought you could destroy TRYPTICON?! Haaa... pathetic!" "He's just laughing at us!" fast.
Nightmare Fuel: When you discover the gigantic Kill Sat you're flying around in is the alternate form of Trypticon, it is... quite creepy to say the least. Especially given Trypticon can talk and begins mocking you in that deep, booming, growling voice.
The true nightmare-tastic moment was after you destroy his Conversion Cog, and everything around your character begins shifting around and you must quickly turn around and fly out his mouth in order to avoid being crushed.
The Problem with Licensed Games: Averted with the PS3, 360, and PC (barely) versions. Cybertron Adventures for the Wii, however, is a mediocre Rail Shooter. Word of God states that the Unreal engine used in War for Cybertron simply doesn't work on the Wii, and that High Moon Studios didn't have the in-house facilities needed to develop a Wii game, so the production had to be farmed out to another developer.
Tier-Induced Scrappy: Not really a scrappy, but very, very few high-level players still play Soldiers.
