[PsychicPsycho]

Modern Warfare 3

Scout Leader: find all 46 pieces of intel in the game- after specifically looking, I found 42, then looked up the rest. One of the ones I missed I thought was particularly cheap- a certain one hidden on a roof in 'Scorched Earth'
Serated Edge: finish a Juggernaut off with a knife- did this on the Toxic Paradise mission. I blasted him a couple times with the Thumper (or whatever that gun is called, it's just like the Thumper) then strafed around knifing him until I got it
Birdie: destroy 2 choppers in a row without being hit while playing survival- got on Resistance. I hid in an archway and shot one chopper down with a standard gun, then blasted the other with a predator
Overachiever: finish all special ops missions on veteran- I was able to do those solo, barring the ones that specifically require 2 players. The hardest was probably Flood the Market, just for the difficulty of living while waiting for the download to finish

[PsychicPsycho]

Modern Warfare 3

Defense Spending: buy every item from the Survival defense armory- probably my most common defensive items to buy were the sentry gun & self revive
Get Rich or Die Trying: reach a current balance of $50000 in a survival game- I just happened upon this in Seatown. I camped out in a room near the edge of the map, bought a sentry turret and used the guns dropped by the enemies. I think I had it by round 23 (+/- a round).
Survivor and Unstoppable: reach level 10 and 15 (respectively) in each survival map- I was expecting getting to wave number X would carry the same difficulty as getting to wave X in zombies. Fortunately that wasn't the case. My least favorite maps were probably Downturn, Fallen (I think) and Hardhat. For some reason I found the Hard ones to be more difficult then the Insane ones.
Arms Dealer: buy every item from the Survival weapons armory- probably bought the Pecheneg & L86 LSW most often- I used the weapons dropped by enemies most of the time.
Danger Zone: buy every item from the Survival air support armory- probably bought a predator missle most frequently
Not on My Watch: rescue all hostages in the special ops mission Negociator- it seems like something stupid happened every time I tried to do this. One time I breached the last room and the game said I shot one of the hostages.

Defeat a certain enemy by stabbing it in the heart.
(the Licker Beta, which can only being stabbed in the heart after being completely disabled... from far away, for the player character's safety)

Bad Blood
During the first fight with Wesker, damage him a set number of times.
(run away from him, throw him off track, and shoot him with the best weapon you got whenever he's got his back turned on you; rinse and repeat before the set time for this fight runs out; a faster way to do this is bringing a Rocket launcher, shooting it at Wesker when he's unaware of your presence, then quickly shooting it with a precise weapon when he grabs it so it explodes on his face, dealing massive damage)

Masters of Removing
Work together to save someone special.
(I won't say who it is because someone might know the characters from the previous games, but it's the most tiring boss battle in the game, because the boss is really trying to kill you with kicks and throws and machine guns and you can't kill the boss or you get a nice game over, so you have to evade the attacks and work together with Sheva to restrain the boss and remove the virus device by shooting it (and you might miss and kill the boss) or tearing it off, it takes a lot of tries until it works either way you choose)
