Games that Bluntly Lie to YouSTALKER: Call of Pripyat: Owl wants a laptop with mercenary movement data on it. The quest tells you to sneak in and steal it without tipping them off. "There's plenty of money to be made here, if you're sneaky."
Correct mission strategy: Kill the entire camp with a frontal assault, sell the good guns, and get paid extra for grabbing the datapads carried by the two leaders. There's actually a script change if you managed to get the data that alerts everyone in camp if you steal it. It's autofail, stealth-wise.
Fallout: New Vegas: NCR quartermaster Contreras wants you to help him with underhanded dealings in exchange for some discounted supplies he's skimming from the base. He sends you to meet a contact with a pass phrase to make a transaction. You get there and the contact doesn't know the pass phrase. Return to Contreras and tell him his contact didn't show. Mission failed.
Correct solution: Tell the guy who's obviously an undercover cop everything you know about Contreras's smuggling and dirty deals. Quest chain aborted, mission complete. Wtf?
Mass Effect 2: "That reaper IFF is some dangerous shit, run ALL THE TESTS before you even THINK about plugging that shit in. Understood, team of highly trained, loyal, and savvy professionals?"
What happens: Meh. Fuck safety, just plug that thing in. What could go wrong??
*Everything goes wrong.*
