Retro Commander is an upcoming classic RTS that looks promising

Noble Master Games, developer of Age of Conquest IV and Demise of Nations will be releasing a new classic RTS with Retro Commander.

Sounds like quite a fully-featured RTS, in the spirit of the classics. With a single-player campaign, AI battles, cross-platform online multiplayer, LAN support, a big mix of unit types across land, sea and air and it even has a day and night cycle with weather too. Overall, as a huge RTS fan I have to admit my excitement over it.

There's no full trailer yet, so take a look at some of the screen shots in the below gallery (click for more):

The game will be sort-of free, with the main version coming with a single map and the rest needs to be purchased either as a full pack or individually. An interesting hybrid model of a demo and a full game. Noble Master have confirmed it's going to release across Linux, macOS, WIndows and mobile too.

More of what it will feature includes:

• Challenging AI for single player games including co-op play with the AI.
• Cross-platform multiplayer over LAN/internet including co-op team and clan games.
• Deep campaign and story line of humanity after a cataclysmic event.
• Troops including infantry, tanks, jets, helicopters, airships, warships, submarines and more.
• Factions each with their own technologies including stealth, laser, shields and more.
• 4X Strategy: eXplore, eXpand, eXploit, and eXterminate.
• Missions including elimination, survival, capture the flag and defense.
• Demanding environment with day-night cycles, rain, wind and solar flare activity.
• Map editor and a central server to host and distribute player-modded maps.
• High scores, playing statistics, achievements and multiplayer ELO-ranking.

Retro Commander appears to be an Early Access release sometime this year on Steam.
