Today, the fine folks over at Valve working on Team Fortress 2 have released the 2013 Scream Fortress event. It should now be available for everyone. If you see an update in your Steam client for TF2 with a size close to ~575 MB, you've likely downloaded the right update. If you're on a data cap of any form, I'd advise holding off on downloading the update all at once.

Helltower and Spell Books

Deviating from past Scream Fortress events, Helltower is a Payload Race map, based on the original version, plr_hightower. Speculation was focused on yet another King of the Hill reskin, but a Payload Race map comes as a nice surprise from Valve.

Spells can also be used on other players, which spices things up. These spells can be found by pushing your team's cart; this prevents the map from being a carbon copy of what Hightower is normally called, tdm/dm_hightower (as people rarely push the cart, especially when given no time limit sans the server's).

Spell books will be given to you the next time you start up the game during the event, so don't miss out!

100+ New Items

Due to the fact that the system used to add new items to the game has been overhauled, the TF2 team is now capable of adding many more items more quickly than with past updates. This is shown in this update, which has added over 100+ new items from the Steam Workshop, made by community contributors. For those interested in looking for craft numbering for these items, the new items added in this update have not been marked as craftable, so don't go wasting that refined metal (or other craft hats)!

There are far too many of these items to list here, so if you want to see what was added, check out TheAnthal's analysis on the reddit post for a list, SteamDB's own xPaw for images of these items, or as always, TF2B for everything at a glance.

Grave Matters

Released last night, Grave Matters is the comic that teased today's update, and continues to follow the "Click image or use space bar to advance" style that Valve has been using in favor of making you click on each and every page, with comics before Blood Brothers. If you haven't figured it out already, if you want to see Grave Matters, just click on the image above.

The associated blog post said that the update would be "not "right now" coming — but you know, we're working on it.". Due to today's release date, this may have came as a surprise, but "we're working on it" may have been "we're just fixing up bugs".

Grave Matters does NOT appear to be the sequel to Ring of Fired, so we may have up to two more comics to go before 2013 wraps up. A Christmas event comic is likely in the woodwork down the line.

If you've reached this far, thanks for taking the time to read this post. You can find me on reddit, Facepunch, and the Steam forums (where I cover various updates for various games, TF2 included), or on Twitter as well. I also spend obscene amounts of time in the #steamdb IRC channel on Freenode, which you can join here (or use an IRC client of preference, such as HexChat).
