Valve has sneakily released a preview of a new DOTA 2 announcer, GLaDOS. Many may have missed the preview with it being a hyperlink from the final full stop of The International 2013 round up blog post. GLaDOS voice actor Ellen McLain can be seen in the blog post, she is pictured with a fan in the final image. The link takes you to an ‘OTA 2′ preview snippet in which McLain as GLaDOS introduces herself to DOTA fans. The GLaDOS announcer pack was confirmed as to be in the making at TI3. The preview (below) isn’t exactly Portal 3 or Half Life 3 Valve fans will surely be rather excited.
