Mongoose in Level Halo

To find the Mongoose enter the Warthog (After you destroy the Monitor)

and keep hugging the left wall. You will go down a pathway and, in the shadows, there is a empty Mongoose.

You can still play the level normally but jumps are much harder to land and infectionforms will roll you over!

If playing on single player you can drive off without the Arbiter, just make sure he does not exit the Warthog

and he will not appear on the back (you also can have him in the back, just get him off the Warthog and he will appear in the

passenger seat)
