. I have gotten 7 kills with sweet tooth's and Kratos's but Radec is little bit harder. Call of duty make this one easier lol.
Kratos, Radec, Sweet Tooth can get 6 kills easily, 7 if your really good Now for parappa the rapper, it only gets 3 kills, fat princess the same, awww forget about if it secures you 3 kills man, its 100% the other 3 guys gets 3+ kills easily, ppl evade, but you can just wait the enemy evades and then you hit= 6 kills. Its the same, just bit longer. There should be a double AP gaining after using parappa the rapper lvl 3 and fat princess should be a little bit longer, or the elfs kills the enemys faster. I haven't try it, but if everyone evades on princess lvl 3, i think its even possible she doesn't get even 1 kill.
Beta problems: when searching a game it freezes, sometimes parappa lvl 3 doesn't work.
