It should need the wrangler. It should be right clicking (with whatever wrench you plan on making with this) makes it you can move you sentry. Though just the remote command you cant chose what your sentry shoots automatically and when your sentry is moving your left imobile to attacks. Add to the stats cant move sentry while being sapped, in spawn, or from a really far range. Similar to Moon Base Alpha moving the sentry father and father away makes the screen more static. When at spawn or far away the sentry can still shoot.
