Sony development teams in the US and UK are helping Team Ico finish up long-in-the-offing PlayStation 3 adventure The Last Guardian, Sony has confirmed.
Speaking in an interview with Wired, Sony Worldwide Studios boss Shuhei Yoshida explained that Sony Santa Monica - the team behind God of War - is among the studios offering help.
"Well, you know, it's not just Santa Monica," he said.
"We have great tech people in Worldwide Studios. We have a central tech group in the US and the UK so we are giving them whatever help they need. Technically, we have the best engineers in the US and Europe, so these teams are helping them, giving advice."
Elsewhere in the interview, Yoshida reiterated that Team Ico is making slow but steady progress on the game, and "sometimes the team has to go back and review things."
"There's a vision that we want to realise but it's very very tough and technical issue that the team is tackling and some plans have to be made to evaluate and go through the process.
"At one point the progress was great, so we talked about the timing of the launch in the past. But now it's making progress, but still not to the level - it's playable, but not to the point that we can talk about the timing of launch."
Team Ico's first project since PlayStation 2 classic Shadow of the Colossus was first announced way back in May 2009, but precious little has been heard since.
Late last year, Eurogamer learned that studio head Fumito Ueda is no longer a permanent Sony employee and is finishing the game on a freelance basis.
