I'm currently about half way through Soldier Dallas (honestly that mod was supposed to come out this month to commemorate Rick May but I didn't have the time to get it done) and I had already started replacing several hundred of Chain's lines with Demoman's so I'm not sure when I'll get to Engineer (hopefully as soon as possible). But I do have a mod coming out soon to tide you over with Engineer in it (hopefully it will be out today or tomorrow)

@JuanMolero76 It's just gonna be a pager mod that replaces the pager guy's voicelines that of Soldier and Engi, I already had it made like last month, just gotta make the video for it before uploading it
