I think you need to get "most bombs planted: accoldes? So if you planted the most bombs within that game you will get the accoldes and that counts as 1 . I might be wrong though... But I thought you could play all 3 modes?

SWEET GOING TO GIVE IT A TRY SO BOTH GAMEMODES WORK I GUESS DOES ANYONE KNOW WHICH GAMEMODE TO PLAY TO GET ACCOLADE

Sabotage is really the easiest mode to do this in, especially if you're running with a strong team. Grab the bomb, run and plant, defend until it blows up. Match ends in under 3 minutes and the person who planted the only bomb will get the accolade every time.

Sad to see Demo had 10k+ people last night and Sabo was only at 1k.
