Splash Damage have been quiet for a while, at least on the PC front, but there have been rumblings of a free to play PC shooter for a while now, and it looks like that Dirty Bomb, announced moments ago, may be that game. A teaser trailer shows a London street, semi-meticulously recreated and strewn with fallen combatants. By semi-meticulously I refer to the fact that there is a signpost that says Bromley on it but the Underground sign is a work of fiction. The copyright for the real one is probably owned by Boris Johnson. So, panic and bomb disposal on the streets of London? Watch.
The site allows players to reserve a name, so Dirty Bomb is almost definitely not a sprawling single player adventure.
