It was said last year that 2.8 Hours Later would not return.

But the zombie chase game that originated in Bristol in 2010 (read the first review here) before heading across the country, where it has now been played by more than 20,000 people, is back next month with a brand new game, Asylum.

And tickets are selling out faster than it takes to run away from one of the undead on your tail.

2.8 Hours Later, made by St Nicholas Street-based Slingshot, has undergone a full rewrite for Asylum.

The infection is at pandemic stage and UK cities are on lock down, isolated by the Government from the zombie-infected badlands.

When these measures fail, the authorities abandon the city, and the once safe zone becomes a prison, overrun with zombies, vigilantes and scavengers.

Asylum will include threats from corrupt police and brutal vigilantes, and its creators promise an even darker tone.

“We felt it was the right time to give the game an overhaul,” says Slingshot co-founder and director, Simon Evans.

“On one level, we’ve had to introduce new safety features and so wanted to re-design the fear factor to counter that. But we also wanted to address the deeper economic and political crisis the country is facing.

“The zombie apocalypse was inspired by a return to Tory cuts and the misery they brought. Now we’re almost four years on and we’re still in recession.

“The zombie infection is the recession, and the culpability, corruption, greed and violence it engenders is the world we live in now.”

Asylum comes to Bristol between September 5 and 7. For more information and to buy tickets, visit www.2.8hourslater.com.
