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: Lost Planet
Demonic Spiders: The turrets from Episode 3-3. Without the right weapons, expect to waste ammo and time attempting to destroy them while you get blown off the train.
Enemy snipers and Revolver-wielding enemies are no exceptions. They're the only non-Akrid enemies that can kill you in one hit (if they put one in your skull), and if you're busy with something else, they won't hesitate to auto-aim for your head, even when you're in the air. Ditto the multiplayer simulator AIs, as they aim for your head by default.
Fan Nickname: Gordiant, the first episode's final boss, was referred as Sir Om Nom Nom, among other names.
Goddamn Bats: The smaller Akrid on the higher difficulties.
That One Boss: It's easier to find one that isn't, even among some of the mini-bosses. However, it's not coming from completely out of left field, since Capcom helped inventNintendo Hard.
That One Level: Chapter 3-2. Filled to the brim with snipers armed with a powerful rifle, a VS with a BFG rifle, and troops with the same BFG rifle.
