This is the only true skill dependent trophy in game when going for it in a more legit way. Ways to increase your score will be kills with special weappns, kills on other players, zombie kills(these give massive points especially if you kill 100-200 in a game, and capturing objectives. Also to get this trophy with friends play a game of swarm domination and play regularly until your team is winning with 195 points. Have whoever has more points than you on ur team quit the game, so you can be leader right before match is won.
