I had the idea for this along time ago. I noticed there weren't very many city maps in RA3. Also, I wanted to practice my texturing skills. After many tweaks, I finally finished this amazing map: Gamma City.

Gamma City is a smaller 4-player map that has two channels and an isthmus in between them. The isthmus is perfect for infantry. Many garrisonable buildings offer good place for people who want to control the map. However, don't forget about the water with 2 ore nodes per channel, it'd be foolish to forget about them. Also they serve as a direct path to strike at your enemy's heels. Beware of battleships! If things are getting tough, players can find some solitude in a small expansion behind them. However, you better make sure there aren't any enemies waiting to prepare a sneak attack!
