There's not enough water in TF2. What water there is is limited to a very few maps (Well, 2Fort, stage 3 Pipeline, Sawmill, etc); and that water is shallow and, well, boring. Underwater battles present different tactical options and setups--some weapons don't work underwater, you can attack or be attacked from any direction, and you run the risk of drowning if you're submerged for too long. But a lot of water can have some serious effects on class balance-- in particular, the Pyro and the Sniper. Flames don't work underwater, and the Sniper can't draw the Huntsman, and risks drowning if scoped too long. So in a water-heavy map, it's vital to provide some concessions for those two classes. Additionally, the Engineer is hurt by huge open spaces: the sentry works best when covering a limited area, so that it's hard for attackers to get a clear shot. To encourage mapmakers to create maps with more water, I propose a related item: the Swimmer's Snorkel, a hat or misc. item that halves drowning damage, gives the user a 10% speed increase in water, and a 10% speed decrease on land. With these points in mind, I came up with a concept for a map that features a lot of water. Enter cp_lake. Map layout Vertical cross-section Tower layout (the images include notes for glass tunnels; but after some discussion on the Steam forums, it's apparent that the Source engine won't handle that) All I have right now is the map design. I have zero experience with mapping in TF2 or any other game. If any more experienced mappers are interested in making this map a reality, I'd love to hear from you! And yes, I know it's a lot to ask, but I'd be happy just getting credit for the idea, as long as this map makes it into the game. Keep in mind that this is just an initial concept layout, so I didn't put much thought into the nitty-gritty of prop/medkit/ammo placement, spawns, or cover just yet. I put more effort into considering the tower layout and its access routes, as I feel that the midpoint will be the hardest to balance between classes. And since I'm not an experienced mapmaker, I'm not very knowledgeable with those aspects. If the map seems interesting, read on for a text description. Central to the map is the titular lake. The lake itself is relatively wide open and quite deep, with few features on the bottom. There should be some cover for Engineers to build forward bases with some degree of protection-- probably sunken boats of some sort. The mid control point is located in a 3-floor communications tower in the middle of the lake. The bottom level is below water level but full of air, with a pair of exits to the lake itself. The main level, just above water level, holds the control point. The upper level is not much more than a balcony with some cover, allowing an attack from above. The tower layout isn't to scale; it's mostly just to show all the access points and options. There are three bridges just above water level that grant access to the main floor; stairs on the outside of the tower leading up to the balcony level; the tunnels leading into the "basement" from the caves; and airlock-thingies (like in Well, but two-way) in the basement for interior access from the water. There are a couple of other things that should be on there, that I couldn't fit in the cross-section without making it too confusing. For example: -stairs leading up from the water -props and cover inside the tower--not just an empty room with a CP Bridges connect the tower to canyons on either side, where RED and BLU's bases lie past a cavern complex. A third bridge leads to a bunker-style doorway leading to the control centre, which is inaccessible. Submerged tunnels also lead to the canyon cave complexes from the central tower. These routes provide long sightlines for the Sniper, but should contain scattered crates and equipment for cover, and for the Pyro to set up ambushes. The Sniper functions better on the bridges, while the Pyro prefers the sealed underwater tunnels where his victims can't douse the flames. The second points lie within cavern complexes just above water level, carved deep into the walls of the canyons. Tunnels connect the main control point room to the bunker entrance, the canyon river, and the bases. There are also stairs that lead down to the underwater tunnels. A one-way gate leads underwater toward the midpoint. Between the second and third points, tunnels (underground) and catwalks (on the canyon walls) connect the caverns and the base. The RED and BLU bases themselves (and final control points) are atop the canyon walls in a hydroelectric dam complex providing power for the tower. Of course, the main attraction of cp_lake would be the possibilities and tactics provided by the canyon rivers and the lake itself: the water provides cover from surface attackers, and swimmers need not fear Pyros or Snipers. Very deep water provides a unique 3-D combat environment where attacks can come from any direction.
