#3 - Currently the hardest medal to obtain is the 6th Medal on the 1st Row labelled "Vengeful". It requires you to Execute 75 Nemeses in Multiplayer to obtain just the Bronze version. To obtain a Vengeful ribbon (counting towards the 75 required) you must be killed 5 times by the same enemy in a match, and then execute that enemy.
There is payback pin in Bad Company 2 that is pretty much the same, and after playing that game for 80+ hours i only got that pin 27 times. And that was for just killing the guy, you could get that from shooting across a map Gears 3 makes you execute the guy.
I can honestly say i love every map, first time ever i enjoy playing every map in a game.
However, if you bring Horde into the mix, obviously there a maps that i think are not so good (for that mode only) just because of the way the defenses are set up and the size of the map it makes it harder.
Im going to be honest and say Uncharted 3. I dont know why. I want to be excited about this game but I just cant
I'm not excited about it either, i don't have a PS3 but i borrowed my friends to play Uncharted 2 when it came out. He asked if i wanted to use it this time too (he doesn't play games only watches Blu-Rays), but i can't be bothered.
