So like the other Hasbro Properties they have Renegade did a dump of Card/Board/ and Role Plying game info for what they have coming for Joe.
Like mentioned in the Pulse Stream GI Joe Mission Critical is a Miniature Board game system. It's using their "Guardian system" so it will be compatible with their PR Heroes of the Grid game. So if anything to go by like that, it will be a base hub in the middle and four location tiles to fight off Cobra forces from inciting panic. Zords from HotG are replaced by vehicles and artillery deck cards that will have three available at a time that will be usable one time for a variable cost of defeated Cobra troopers instead of Zords that stick around after defeating 6 foot soldier types. Cover Girl and Gung Ho are two of the playable Joes. Major Blood and Dr. Mindbender shown as Cobra Operatives to fight. Special Preorder bonus figure of Snake-Eyes in his classic pose from his first card art.
The Deck Building Game is getting a Small box expansion called "Shadow of the Serpent" adding in Serpentor and Hawk to the Larger Base set needed to play one of the Small Box sets. And another expansion called Coldsnap that involves the Dreadnoks and the Weather Dominator is slated for fall.
The RPG is set to launch later this month and had a bunch of new stuff to supplement it.
A Joe Miniatures pack, which are smaller than the Mission Critical ones designed to fit 1 inch square map tiles. Gray and unpainted figures included are Airtight, Bazooka,
Cover Girl, Duke, Gung Ho, Jinx, Lady Jaye, Mutt & Junkyard, Rock ‘N Roll, Scarlett, Snake Eyes, and Stalker.
A GM Screen with a level 2 adventure called the Emerald Oubliette. Jungle locale adventure.
A new Adventure book for Joes level 3-6 called Operation Cold Iron to play after the adventure in the cold. Sounds like it'll have some stats for some colder based vehicles like the Snow Cat.
Cobra based sourcebook is coming. as well as Cobra Dice and bag to counter the Joe themed ones already up for order.
And Later there is a Joe Character Journal coming. Each of the Hasbro themed RPG games will have these coming but each are fancy extended character Sheets. Though it sounds like they may make it look like the old school file cards inside.
