Valve does not often make use of open playtesting, in keeping with the company's tradition of tightly controlling what information they release to the public. However, both Dota 2 and were openly playtested, with beta invites being distributed to (and in some cases by) volunteers. Valve also has a general beta signup form on their website; this survey is intended to recruit testers both in the Seattle/Bellevue area and from other locations, to test new games and gaming hardware that Valve is developing.
