The perpetually patched Team Fortress 2 is about to get its "largest update ever" (dare we say heaviest?) next week on August 19. In the lead-up, Valve is releasing new information and screenshots about the patch each day, as well as a "special installment to the 'Meet the Team' series of video shorts," according to the press release. The community map cp_steel was revealed on the first day.

Besides new weapons and achievements for the Heavy class, the next update will include new multiplayer maps and a "brand new gameplay mode," possibly related to the new type of environment we heard about earlier this month. As with the other updates, Valve is offering a free Team Fortress 2 weekend starting August 22 at 2pm ET.
