This thread is just here for people to share their thoughts on what they think would be cool unlockables for TF2 if their is DLC or maybe a sequel anyway my ideas (With characters I hope get into a Poker Night game in the future if there ever is a sequel or DLC)...
Sam-The Big Kill (It would be cool to see this return with The Max hat)
Max-Max's servered head (Again it would be cool to see it return for people who missed out on it)
Strong Bad-Homestar Cap (Homestar's hat) and A Cheating friend which is a small The Cheat teddy like the balloonicorn.
Marty McFly-Skateboard (Is a melee weapon)
Wallace & Gromit-Anti Pesto hat (The descreption could be "A hat that shows you are a proud worker in Anti Pesto and look there is even a signature from Wallace")
Guybrush Threepwood-The Mighty Pirate (a wig that looks like Guybrush's hair), The Loyal first mate (Winslow's hat and it could say "There's 2 things a good first mate needs their pirate hat and a good map.) and another item could be called The Pirate Beard which is LeChuck's beard.
Anyway that's all I could think off but go ahead and share your ideas on what you think would be cool and fun TF2 unlocks :)
