The loki can drop 3 crates that give random kill streaks and it is possible to get another loki from a loki dropped crate. It also drops a juggernaut side kick that protects its owner and can be commanded while using the loki. After the loki ends it functions as a squad member.
Loki isn't hard to get , get 10 kill streak and allow the kill streaks pile up the rest. Say get a gryphon and kill 5 players and done, loki.
