Nuclear Dawn

Overheal

This one looks like a new Source Engine Game that takes after Natural Selection. Team vs. Team gameplay with unit classes; Each team has a Commander that can oversee the battlefield via RTS to assign players into squads, give them assignments, and build bases along with an entire tech tree. Everyone else on the team plays via FPS.

Nuclear Dawn is the first game to offer a full FPS and RTS experience without crippling or diluting either side of the game.
Play as a soldier in a war-torn post-apocalyptic landscape, modeled on modern cities, and take the fight to your enemies as armored, assault or stealth infantry, using various weapons and load outs to accomplish your objectives. The first person shooter action in Nuclear Dawn is hard, fast and unforgiving, with weapons that rely on skill and tactics more than on twitch reflexes and map memorization.
Learn your roles, the strengths and weaknesses of each class, and use them to their fullest to lay waste to your enemies, in specially designed environments that force you to exploit terrain and cover to stand a chance in tomorrow's war.
Then, take Nuclear Dawn above the action, and play as the commander. Organize your fellow players in squads, and assign them to tactical objectives. Plan the resource routes for your army, and production of your structures for forward deployment.
Exploit the terrain and resource point locations to block your enemies’ tactical advance, and crush their plans in an iron fist. Research and implement new technology to give your soldiers the edge on the battlefield, and set up forward bases to lead the assault on your enemies, with full defensive and offensive structures to choose from and upgrade to build your perfect fortress.

• Two distinct factions: the Empire and the Consortium
• Four playable classes, each with three sub-class loadouts, plus the commander role
• Over a dozen weapons across the various classes, and factions
• Each faction has a completely separate base-building paradigm, with different workflows and tech trees
• Upgrade weapons, buildings and classes with powerful Golden Age blueprints
• Build Doomsday weapons with pre-war technology that will give you the deadliest edge in battle
• Travel across the largest, most detailed maps built in Source multiplayer to date.

No official release date yet but it looks close to finished and its previously been teased at a 2010 launch. It now appears on Steam's top 10 Coming Soon list. Once upon a time TF2 was being designed around the same idea.

The dev team still have some polishing to do for the game, but the initial aim was to hit for an October release but I suspect it will be November.

Beta testing has yet to commence, which I think will certainly begin as a closed test.
