In Galaxy Defenders: Extinction Protocol, an expansion for Galaxy Defenders, the agents head to the home planet of the invaders to fight the final battle to save the Galaxy from extinction. Armed with a new generation of weapons and wearing awesome Power Armor, the agents are prepared to fight the worst enemy they have ever faced. New Features: In Extinction Protocol, the journey through the six missions begins as the Agents reach the Alien planet. To fight their enemy, they must enter into a darkness made of caves and corridors, across underground lakes, through alien temples, and face the ultimate challenge in the terrible Queen’s chamber. The underground of the alien planet is formed by thousands of narrowing corridors and caves. To properly represent this new setting, a new system of modular tiles creates the game board, using smaller tiles with a variable number of areas. The tiles remain fully compatible with all the maps of the GD Universe to create custom missions. This new system, combined with standard map tiles create an unique game experience. Below the ground, alien menaces lurk in the shadows. Insidious opponents – and sometimes, precious resources – will appear on the battlefield as Stationary Signals, that will only be revealed when you are close to them… In addition, the doors of the underground Alien Base are protected by an enhanced security system that allows the access only to the owners of the right encrypted keys! To accomplish the final task, our agents will be dressed and armed like gods of war! Thanks to the new GD-Ranks each agent can acquire new skills and tactics, including tactics that can be used without spending actions. More important, they will make the battlefield to quake with their Power Armors, the ultimate weapons created by Mankind. The use of these exoskeletons empowers the Agents with new abilities and allow the Agency to deploy devastating firepower against their Alien opponents. Each Power Armor is represented by a unique figure and by its Power Armor Profile Sheet. Unlike Power Suits, that are used by any character, each Agent uses a unique style of armor. Each armor has completely different weapons and powers, and transforms the Agent in a lethal war machine!
