Valve showcased more footage from the co-op sections of Portal 2 last night at the VGAs in Los Angeles.
A new trailer, which you can see below, shows the creation of two new Apeture Science robots. They make lots of cool squeaking sounds. When they recognise each other for the first time, it actually approaches something 'cute'.
We've seen the pair before, of course - with Valve's last co-op trailer. Just like that video, the VGA reveal is set to a thumping soundtrack.
Portal 2 will be released on April 20 in the US and April 22 in the UK and Europe for PS3, 360 and PC.
