A very nice game, where the atmospherics are great and really give a good ambience of what it would be like to be inside the dark and claustrophobic tunnels. The tension inside the game is built up nicely with a fantastic creepy ending.
The only minor point was the walking did feel a little bit slow at times and stifled some of the build up but other than that a great solid experience .
I look forward to playing part 2 and see how this continues on , it will be interesting to see how this develops.
