Hell Let Loose Climbing

It is possible to climb on walls, buildings, towers, grain silos and other obstacles throughout the map

=Climbing=

Running while Holding Jump
You can parkour across the map if you run while holding the space bar (with an auto-run macro) - you will auto-vault walls while running. This technique can be used for some of the trickier climbs as well. When doing a climb DON't LET GO OF JUMP!

Run Jump
You can make some climbs while doing a running jump that you can't from a standing jump - even if you start your run at the edge of the object.

Prone Jumps
This technique takes some practice - While doing a run jump against a obstacle that is about eye level hit the prone key at the apex of your jump, this will let you LAND on the object and you can then unprone on top of the object. This skill is well worth the time it takes to learn.

Assisted Climbing
Trucks / Half Tracks / Nodes / Barricades can be placed next to buildings/walls to allow you to climb up easily! When in doubt use a truck!

=Climbable objects=

Walls
Most walls in the game are climbable

Buildings
50% of the buildings in the game are climbable - Some have invisible walls at the lip, but some are just difficult jumps - experiment to see which is which.

Grain Hoppers
All grain hoopers are climbable in the game. You may need assistance to get the first climb onto the wooded platform next to the hopper.

It is possible to jump from the mud under the grain hopper directly to the wood scaffolding with a running prone jump. This is harder than the truck method. Make sure you position yourself offset from the grain hopper, you don't want to hit your head when jumping.

Hedgerows
Some hedgerows are actually secret walls you can climb up on.

Churches
Some of the churches can be climbed on

Chimneys
If you can get to the roof you can probably get on the chimney. Chimney's are excellent machine gun mounts.

Warehouses
If you see a scafolding on a building you can climb on it! Just park a truck under the scaffolding.

Cranes
All cranes in the game are climbable.

Gabled/Attic Windows
Crouching in the window Jumping left or right you can get onto roofs. If you can shoot through the edge of the window with colliding with the wood, then you can probably climb through it.

Barns
Park a truck next to the barn, then jump to the cutout below the roof. Go prone and crawl around the corner to the short side of the building, then eventually you can stand up and jump to the roof.
