The Half-Life and Black Mesa subcommunites have the "Error" and "Error Success" reaction images respectively. I think there should be reaction images of the Portal 2 variant of the Error model as well as the Source 2 Error model in the future. EDIT: Check the comments!
New Portal emote ideas: - Space Core - Security Camera - Prima Donna Turret/Fat Turret - Franken Turret
:deadass: look in the comments for transparent version
:gtroll: for gmod or...
Health Vial emote
