Each company has its own battle map areas, which follows as 4-1 is owned by MMO, 4-2 by EIC, and 4-3 by VRU, while 4-4 is not owned by any company, and 4-5 is inhabited by boss and uber type aliens. Each battle map area does not contain any ore, resources, or aliens (besides 4-5 having uber type); all the battle maps have bonus boxes which even contain times x1.5 the content. 4-4 is slightly a higher traffic map due to having three portals close together in the middle which lead to 4-1, 4-2, and 4-3.
