TF2Maps.net is hosting their 72-hour TF2 Jam! This season instead of making just maps, they're encouraging all forms of TF2-related creativity: maps, models, SFM builds, hats, fanfiction, poetry, HUDs, art passes, competitive tournaments, and anything else! The Jam starts 10am PST, January 29th and runs for 72 hours, ending at 10am PST Feb 1st. Visit the TF2M Thread to learn more.
