I find this map actually pretty nice.
It is based around a hub from where you get into 3 differently themed parts. A red brick base part, a green swampy something and a blue brick/metal mixture. Windtunnels are a main element of this map as is water (hence the title).

Considering the age I'd rate this "nice".

(I've not played this but ...)

I'm not fond of wind-tunnels. They always feel like a cheat to me -- just plucking you up from one part of the map and dumping you in another, like a teleporter. I admire maps that have a sense of place and solidity, where you progress from one point to another instead of being put there.

Down with wind-tunnels and teleporters!

Played on nightmare. 5/6 secrets found (missed the first one), plus many others not numbered in the map.

Quite good.

The brushwork is just above average for the year, but loop shaped with some non-linear bits layout, size and secrets are good. Combat is decent and varied. Difficulty lower than ID maps. Ammo/health/armor in a quantity like ID maps. The secrets range from decent to original, and from them stands out the last one with the LG, and the big secret area. There is also many secret or side areas with no trigger_secret entity with some goodies.
