Alien Invasion will breathe new life into the franchise. Players will be able to build their own cities and defend them against the imposing alien threat. Player built cities aren’t a hut in the middle of nowhere, either. Guilds will be able to team up with four other guilds to build a metropolis on the existing map. Cities will include player run shops that transfer funds directly into the guild’s bank, hire guards to patrol streets and borders, build grid access points (which allow people to reach your city from the grid, as well) and a total of five guild headquarters.
