Apparently you can. Glen McCracken is taking on Modern Warfare 2, attempting to reach level 70 without killing anybody. He’s been going for a while, he’s up to level 21.
“Along with his astonishing zero kills, Glen has died 1,339 times. I caught up with gaming’s favorite pacifistic player, and although he admits that “things are already starting to slow down,” he remains positive. “With my Tactical Insertion and smoke grenade combo, I’m getting more points than ever,” Glen says confidently.”
Modern Warfare is a team game – and while you’d think having a player deliberately not killing people would be an impediment to team success – he has a winning record.
“Glen isn’t killing anyone, but how are his point grabbing techniques affecting his teams? Apparently, you’ll want him by your side. Glen has a winning record. He has 62 wins and 52 loses so far.”
