Prerelease:Team Fortress 2

This page details prerelease information and/or media for Team Fortress 2.

This article is a work in progress. ...Well, all the articles here are, in a way. But this one moreso, and the article may contain incomplete information and editor's notes.

To do: Make a new subpage for weapons/cosmetics/etc "leaked" through official media I haven't actually uploaded stuff for this page yet, but I'll get around to it soon ~ TF2CC Fill this main Prerelease page up with all the known prerelease medis (concept art, early playtest screenshots, etc.)

Many in-development items and concepts have been accidentally revealed by Valve throughout the years in various ways, with a lot of them never seeing a proper release.

Tiered Attributes

In July of 2010, a total of three hundred and fifty-five attributes were found to have been added to the Steam API, but were not added to the attribute list in the game files. They were all standard existing attributes from the game, but with five copies of each attribute. Each of the five attribute copies had their names prefixed with "Tier" and a number ranging from 1 to 5, e.g. "Tier 1", "Tier 2", etc. Unlike the standard attributes ingame which are able to have their values changed, these tiered attributes had their values pre-set, with each tier being a slight upgrade to the previous tier in most cases.

It is unknown what these attributes were to be used for, but speculation includes either the attributes being for some form of an item levelling system, or that they were Raid Mode's version of Mann vs Machine's Upgrade Station. Supporting the latter idea, Raid Mode as a concept dates back to around the same time as the inclusion of these attributes, with filenames for Raid Mode bosses being found in cp_degrootkeep.lst when it was added to the game with the map itself in the Australian Christmas 2010 update.
