Pros:

Nice looking level design.
Different from the usual urban setting of most maps.
Very atmospheric.

Cons:

Can be a bit unclear where you need to go.
Some floating items.
Can clearly see where the map and skybox connect on some maps.

Conclusion:

Definitely a very good looking map. It does have its share of bugs though, Like floating items and i was charged off the mountain at the end of a map and me and the charger got stuck. And its very open, so its quite possible to get lost. I'd recommend playing it for a change of pace.

Pros:

Nice Design.
Skins for specials.
Skins for survivors.
Old school FPS style, Keys and all.
Leafo campaign.

Cons:

Had issues with keys not registering, Had to restart a few times.
Had issues starting finale.
Few other glitches.
Last leafo campaign.

Conclusion:

Its the same great quality from the silent hill map, but shorter and with a few bugs included. Its still worth a playthrough and its a shame to see you go.
