The Energon Pub

I`ve been playing WFC for half a year or so now. I`ve got all the PS3 Trophies for it, but i`m still trying to get all the Multiplayer Challenges omplet. MAN, they are HARSH. Seriously, 4 times 7 killstreak in a match? 50 Headshots - with the Neutron Rifle? ARE THEY MAD?

Now, point of this thread; what trophies/challenges in a videogame have you had the hardest time completing? Please tell what game, what Trophy/challenge, and what you have to do do get it. Example;

Transformers: War For Cybertron;

Challenge, "Stun And Gun"; Eliminate 50 opponents with the Energon Battle Pistol after stunning them with the Decoy Trap.

Challenge, "Bullseye!"; Eleminate 10 opponents with the Photon Burst Rifle after they have been Marked by a Scout.

#2 is SO dang hard!

Getting Gold and Silver medals on Rouge Leader on the GC - I simply burned the game into my retina and decided that doing the same level 300 times+ was actually worth it.
