Had a grunt in a ghost splatter two elites via the old Sudden acceleration sideways out of the map glitch from Reach. Also a funny thing to have happen is in the last mission in episode five, on heroic or higher try to line up a splatter of the lot of them. Interesting things tend to happen other than the expected 20 kill splatters.
this one time i shot a guy with the barinary rifle 2 times he did not die and he shot me 1 time with a pistol and that killed me no gamer tag on him kinda moved like the ghosts of halo 2(look that up on youtube) and then i got booted this was on matchmaking by the way
In the last level of the campaign while playing with a friend, I gernaded a Knight out of the map and if you get them off the edge they stop moving and float down through the bottom of the map.
