Valve is looking for playtesters to come try out all of their cool new gadgets and games.
They want Seattle/Bellevue-based testers for now, but they also might have plans for remote playtesting in the future, according to Valve's Burton Johnsey, who posted on Steam's forums to announce the playtesting:
We're looking for folks to come to Valve and playtest both released and unreleased versions of our games as well as play around with some of our hardware prototypes. If you have interest in stopping by (most sessions last around an hour), please fill out the survey below. We're looking for people local to the Seattle/Bellevue area, but you're welcome to fill out the survey no matter where you live as we may have plans for remote playtests in the future.
Thanks for your interest in helping us make better products!
We are looking to add international support in the future. For now though, playtesting will be US only.
Could they be testing Half-Life 3? Wearable computing? Ricochet 2? The world may never know.
