here is metal gear rex from my youtube channel , i hopy you will enjoy it, remember that its manual walking with this mech so practice with the leg moving so you will get it right. and use indestructible facilities on because Rex Weights a alot and will destroy the plane field when stepping and may also break its legs so unbreakable joints is adviced also

here is the list of mods and links to them that i used in this fella:
