XenoCommand

From BoardGameGeek:

XenoCommand is an elite international organization tasked with countering alien invasions of Earth. Each player starts with a modular base and several structures. Roll the dice to gain resources that correspond to your structures. Spend gold and tech to expand your base, upgrade your defenses, recruit agents and buy vehicles. But as each time you roll the dice, the invader's plans advance, bringing you closer to the inevitable invasion. When the UFOs descend on Earth, the invaders will breech your base! The only way to survive is to spend wisely, position strategically, and cooperate with your fellow defenders. Wipe out the invaders or capture them to steal their secrets to create advanced weaponry! Survive the onslaught of invader attacks and team up to send your forces into space for a climactic battle against the invader Mothership!
