Team Fortress 2 Mini-Sentry

I couldn’t find the new sentry in any TF2 folder.
Although sentry is not in there, all the new engie weapons and new maps are in place.
Maybe I just missed a folder or I have to unpack it from somewhere?

Everything genious is easy.
All I needed is a bodygroup changer and a first-level-sentry.
Right-click a few times to get a skin of a mini-sentry and then just subgroup 1 and bodygroup 1 for the lamp on top of it.
