You should all remember my love for The 7th Guest – I loved it back in the day and I loved it when it was re-released for the iPhone last year.

The iPhone version was replicated almost exactly as I remembered it – but there was one puzzle missing. The dreaded Microscope puzzle where you competed against Stauf in a battle of germ warfare. The goal was to gain the majority of a board which is seven squares by seven squares. However Stauf is a cheat so good luck trying to beat him at his own game.

It is only currently available on iPad – but it does have Game Center support so you can see who is closer to beating Stauf and there seven difficulty levels so you don’t go completely mad.

Check out the trailer for more of The 7th Guest: Infection and go buy it now on the iTunes store.
