Yeah Starscream, the Clan pack will be a plug-in component for BTA Core that will get an independent Nexus page because the Clans will not deign to share a release page with those filthy Freebirths, but it WILL get a Nexus page. Patrons get it first and exclusively for a little while, but everyone will get it 100% for sure, that has never been in doubt. I don't permanently gate my content. Patrons get betas, get it early, and at the highest levels get to have basically 1on1 with me while I play the pack for their amusement and get to cheer and throw fruit when I mess up, but ALL people will have access to the pack, patrons just get bonuses.
As for what the pack will contain, it will be the following (as of this writing):
-43 Clanmech chassis, each with every canon variant extant in the early 3060s.
-Every piece of extant Clan technology in the early 3060s, experimental or production.
-A full Inner Sphere Star Map, remixed and edited for the FedCom Civil War by hand so there's high attention to detail (where possible and where it wouldn't add days of work for tiny changes, I'm only one man).
-Full faction spawning and a bunch of new factions, all canon (including one that even RT forgot

).
-Clan-specific contracts that spawn Clan mechs in Stars as is lore appropriate.
-Clan tanks, though number yet to be determined.
-Some Clan pilots in the hiring halls probably.
-Probably more if I can find time for it. I'd love to do some Flashpoints and other stuff but that's a big time addition.
If that's appealing to your sensibilities, then check it out and hit me up on Discord, I'm happy to talk about it and I stream demos every now and then.
