I admit that if no one told me Ambush Keen Pilgrims was a combination of two previous maps, I wouldn't have known. Firstly because I hadn't played either of the previous, and secondly because the map(s?) carry an Atlantean theme similar to Pingu's last, The Journey Home, which is quite seamless.

Ambush Keen Pilgrims is in fact made up of two of Pingu's DM maps: Daydream and Return To Atlantis. They have been merged by Mike Woodham under the guidance of none other than Mr. Shambler. The result? A curvy, and somewhat difficult SP map. You'll start at the bottom of a spiral staircase, and upon making your way up you'll have to start shooting. I found myself continually being challenged by monsters, ogres mainly, on a level one up from me. Ambush Keen Pilgrims is very vertical due to its DM origins, and those ogres can really take advantage of this design. The map is very interconnective and you will often return to areas you've cleared out, only on ledges or walkways. After a lot of combat the architecture gets more spectacular in a semicircular outdoor area, and from there you progress to the map's conclusion.

The last part of the map is somewhat confusing and gets a little harder. Ogres and Hell Knights are now replaced by Vores and Shamblers, and I found myself in a hit-and-run situation. Once I managed to strafe around the corner and fire enough rockets/nails, an exit portal became accessable and the level drew to a close.

Ambush Keen Pilgrims is a decent experience, but I prefer The Journey Home.

I thought the most impressive aspect of the level is the way the two levels have been merged together. There is still really just one path throughout, but having known the deathmatch levels already it was interesting to discover where Mike would make you go to next. Gameplay was good, but could have been tougher. Whereas at the end, like Tronyn said, it just became a bit messy and I didn't even know what I was supposed to be doing.
