There were 2... acquire malfeasance and protect the runner..100 modes collected by 1 player, never losing a single mote and winning the game.
That page says: [quote] but there are also two secret Triumphs. One is to earn the Malfeasance exotic hand cannon through an exotic quest that did not appear until last week. The second secret Triumph is called Protect the Runner, which requires one player to deposit 100 Motes during a match without losing any, and winning the match. This is one players will definitely need to do within a fireteam.[/quote]
