The Walking Machine is one of the vehicles from Metal Slug 4.


It is basically a variant of the Camel Slug, but possesses a lower profile, increasing survivability by some amount. It can also jump higher than all of the slugs. Also, when rolling bombs come at the walking machine, it won't be harmed. It will just roll past this machine.


  • The design of this slug is possibly based on the Mutated Soldiers in Metal Slug 2 and Metal Slug X.
  • There is a statue that looks like the mutated soldiers in the entrance gate where you take the zombie route.
  • It also appears in Metal Slug Defense and Metal Slug Attack as Nadia's special attack, she calls and rides it until she is killed.
  • There is also upgraded version of Walking Machine introduced in Metal Slug Attack. It was painted blue, had different head, and the vulcan cannon is removed, changed to gatling gun that placed inside it also has larger backpack for storing custom air mine
