    Phillip says Avoid It!

    This one starts quite well with a very simple corridor leading to an even simpler puzzle.It’s too short to describe each area without spoiling it for you but it’s clear from the beginning that this is an amateurish map.

    The last section leaves no doubt and the ending is just terrrrrrible. (Extra Rs added for emphasis!)

    My Recommendation

    I seriously considered giving it an AVOID IT recommendation but felt that the earlier parts deserved to be played by some players.

    This map lacks details within each section and a proper ending.

    Maybe?

    Mapping. Looked OK
    Combat. Sparse

    The worst bit is at the end.
    You get to 3 Striders and the map ends before you can take a shot!

    Let me at those Striders.
