using a simple mod, enable walking on walls for halo pc. just download some software, and check some boxes!
Step 1: Downloads...
you can get it here
Step 2: Open Hmt
First off start up HMT
Now before we go on press the windows button and "e" or windows explorer
go to OS>Program Files>Microsoft Games>Halo
make a new folder named BACKUP
Copy everything in the maps folder and paste into BACKUP
this is for when you want to revert back to normal halo gameplay
okay continuing... Go back to HMT and go to Open>OS>Program Files>Microsoft Games>Halo>Maps
Open up a multiplayer map like bloodgulch
os means you go to your c drive. just go to start>my computer> c drive.
Step 3: Check Some Stuff...
open the tag: [bipd] Biped (2 items), it should be fourth from the top
just click the little plus sign on the left of it, and it should open.
two tags will appear underneath it. click on one.
on the right of the hmt window, you'll see a tag editor box.
at the top, there'll be two check boxes, one will say immune to falling, the other will say walk on walls. click both.
now repeat that, but with the second tag.
when you're done, just close the hmt window, everything is saved already.
Step 4: How to Use, and Extras
you can also walk on bases, vehicles, and even other people!
it basicly makes your feet stick to everything, so you can walk on anything solid. there is a "ceiling" below the sky you see. if you go as high as you can on a wall, then try to walk on the "ceiling".
it'll look like your flying, or walking through thin air.
to get down, just jump (press spacebar) and you'll fall.
have fun and experiment!
