Something called Warhammer 40,000: Kill Team has popped up on the Australian Classification Board site.
The listing, spotted by Joystiq, doesn't give much away other than that it's been rated 'M for Mature' and is developed by THQ Digital Studios UK – the same outfit behind the recent Red Faction: Battlegrounds downloadable title.
Could it be some kind of tie-in with the impending Warhammer 40,000: Space Marine shooter perhaps? We're onto THQ now in search of answers.
