Funny story.
On my legendary play through
(FINNALLY FINISHED BTW F**K YES!)
of that level i played through without dying, utilising rockets to take out three banshees and then taking my own mongoose.
After that i made the jump and waited for Emile.
He drove forward slowly got a boost of speed and made the jump,
He then flew through the air and hit the edge of the ledge head on and fell,
Down down down outside the map, into the distance.
I then preceeded to do the next spot in one building taking on countless brutes from hell and jackal with lazers and needle rifles all with a shotgun and rockets. Useless when sticking your head out means death. So i eventually got a DMR and managed to live scruffily and met multiple challenges, the wraith was hell and took 5 rockets to die....
Eventually Emile came back after the cutscene and proceeded to be as helpful as a blind watchdog, repeatedly driving me into the scarabs. I made it through the level in about an hour and a half and practically forgot emile was there considering he just drove a ghost and didnt shoot it, then hid when i fought two hunters and 6 skirmisher alone....
F**k emile.
