This mission is identical, mission tasks and objectives, to the original version of Backup, Back Down. The Extreme set of rules is pretty self-explanatory, as it basically means that enemies will deal more damage to you, meaning that direct combat is not something you want to do. You have full use of your tools and Buddies in these missions, except for the Chicken Hat and Reflex Mode.
Remember that you can use a vehicle of your own (which you should have by now), as well as D-Horse, to block the enemy vehicles from advancing too far. This doesn’t stop them for too long, however, as they will blow up the vehicle and honk their horn to get the horse to move. Other than the enemy dealing more damage and not having Reflex Mode, this mission isn’t any different than the normal version.
