THis isnt really an hack or glitch its a mix between both.
THe HAcks needed are:
-Dead HAck
-Low gravity
-Plant gernade M67 HAck (optional) but makes it way easier
**remember to turn off all other health hacks EX. Bullet clipping or infinite health**

Weapons:
-AT4/RPG
-M67
-Z..Burst

House:
Alright basically you just shoot your self onto the top of the house, stand on railing near backdoor and crouch, look down and shoot it takes a couple of times to get on top of house.

Barn:
The barn is the easiest if you have the plant gernade hack on, goto the back of the barn closest to the wooden thing sticking out of the ground, and lay a gernade near the barn but not to close and take a few steps back. THen run towards the gernade, if timed right you should explode on to the top of the barn.
**This could also work with pmns or claymores**
Not really a hack but its much fun when you get the hang of it.
