Portal 2 Perpetual Testing gets humorous trailer
GTTV’s aired the first trailer for the Perpetual Testing DLC for Portal 2. The trailer features a voiceover from JK Simmons as Cave Johnson – at least, it could be: we reckon it might be a soundalike. Still funny, mind.
The DLC launches on PC and Mac on May 8. Get the trailer below.
