Alliances
Each federation can only have alliance with up to two federations only. Members
in the same alliance are not permitted to attack each other.Why do you need an
alliance? Let’s say ABC Federation is at war with XYZ Federation. Your federation
is also at war with XYZ Federation. It is only wise to be an ally of XYZ Federation
so that you can plan your war strategies together.Alternatively, if your federation’s
goals are about the same as another federation’s goals, it is only logical to work
together towards the common goal.
