The map's central core branches off into underground sections of sewer and tunnel, that go on for quite a ways, but are distinct and well-marked enough that it's not possible to get lost, and you always have a sense of where you're going. You get a bit of underwater combat in which is nice, but more would have been good. One of the cooler things about the layout is the centrality of the Gold and Silver Key doors. You are continually returning to the same hub. The secrets that I found were cool, so keep your eyes open.

Throughout, architecture is built tidily and on a good scale. Angles are used to create visual interest throughout, even in the simple hallways - there's nothing really blocky here. Details like inset lights and machinery also create visual appeal in the various sections. Lighting is good, always sourced. The texturing is particularly good, always clean and well aligned. Animated textures here and there give a good sense of functionality. With a good sense of progression, a little bit of exploration, and steadily escalating gameplay punctuated by challenging ambushes, Wicked Base is a solid base map.
