Probably the easiest way to finish the x5 and x4 and x3 challenges are in deathmatch... Watch u do is create a map that is just one single strip long and then wen u get enough rage(in free for all) just wait and camp out in a corner until they are all in a lump and just beat them down.. Another easy way is to get the double or 5x damage thing. It makes it so incredibley easy its scary. Hopes this helps

P.S. Post some of your helpful guides if u want to
To get those medals just make a map with on long strip of land and make an enclosed area so that all the enemys are cramped up together but put the settings on Rage Match...
