Annex: Conquer the World is an anime themed real time strategy game that brings fast paced combat with a diverse arsenal. Play as one of four factions: The East Ocean Alliance, the NEO Republic, the Shadow Organization, or the Renegades as they struggle for dominance all over the world, competing for a priceless red mineral. The game now contains 4 factions, over 30 tech trees, original maps, and tileset. Built using open source RTS MegaGlest, the focus of the game is multi-player and single-player skirmishes. However there are also scripted scenarios/missions!
So here is something cool instead of cute :P
The fortress is a tech building (same type as Silo or Shadow Lab) its required to build Neo republic's strongest vehicles, the Goliath Tank and Troop Crawler.
Unlike other tech buildings, the Fortress is both heavily armored and armed with anti-armor missiles. Like the Alliance Silo, the Republic Fortress stores their nuclear missile.
A Fortress, supplemented with bunkers and AA turrets can be an difficult obstacle to overcome.
