An urban zombie chase game is returning to Glasgow this summer with an incredible new plot for fans of the genre.

2.8 Hours Later, created by game designers Slingshot, will come to the city on June 11, 12, 13, 19 and 20.

The new plot focuses on the rapidly depleting number of living humans left. Five years after the original zombie infection broke out, a devastating discovery has been made; a weaker strain of the virus has infected our entire species and, as a result, no children have been born in four years.

This epic street game will see participants join a resistance movement as they attempt to locate the last remaining group of uninfected children left on earth.

The only way to prevent humanity's extinction is to reach them before someone, or something, else does. The mission is fraught with danger; will players save themselves or save the species?

The 2015 version of the game is called Ruin which follows on from last year's Survival, but this time round the quest is more urgent than ever as the existence of the human species hangs in the balance.

To locate the children and bring them to safety, participants will have to leave their zombie proof headquarters at Asylum and break in to a quarantined slum run by a brutal warlord and that is rife with the infected.

Armed with little more than a map, players will have to complete physical as well as mental tasks whilst evading the zombie hordes roaming the city streets.

They will have to infiltrate the warlord's gang, evade police capture and carry out their search and rescue for the children.

Players will need to do all this without being caught by the rampaging zombies. The further from Asylum they get, the more perilous their task becomes.

Characters within the game are played by convincing actors in full costume and make-up. Players who are 'caught' by the living dead will be marked with invisible ink signifying infection.

The game, developed by award-winning game designers, Slingshot, is now in its sixth year, with over 60,000 people having already taken part in 2.8 Hours Later to date.

This year alone there were over 18,000 participants, 5,000 of which played in the London games over Halloween.

Simon Evans, who co-founded 2.8 Hours Later with his business partner Simon Johnson, said: "We visited Glasgow last year and as the game continues to grow in popularity we thought we'd bring it back to the city for an even more spectacular event.

"People are always looking for something that will drag them out of their comfort zone and Ruin will do just that.

"Adrenaline and fear will push participants forward but they'll need to be careful not to let terror overwhelm them; you will need cunning as well as speed.

"In 2015, the game will offer a whole host of new challenges for our players to contend with and characters they'll meet which will make the experience completely different to previous years.

"The mission is new, the story is fresh, the gameplay is unlike anything that has come before in 2.8 Hours Later."

He added: "This offers a unique chance for players to act the lead role in a zombie video game or horror movie. People tend to sign up as a team, but you can sign up individually. Our only restriction is you have to be over 18 to play."

Tickets start from £38 per person.
