For everyone out there still truckin' away at TF2 all these years later, we've got a neat little shoutout to Applejack here in the recent update they released yesterday. In the patch notes:
Updated ctf_applejack
- Added block bullets to some stores
- Unblocked a window at mid, allowing Snipers to shot across the middle hut
- Removed the missing texture in BLU spawn
- Gave a chicken a friend, because friendship is magic
It's always fun to see poni references these days, especially with how rare they've become.
Thanks to Spectral Bolt for the heads up.
