HOST 3.22.007 implements a different alliance system ("locking alliance friendly codes"). PHost does not implement this system, because PHost's system is older and we believe it's more flexible.
When you offer an alliance to another player in HOST, this has the following effects:
- They will be immune to your minefields.
- They will not be able to sweep your minefields.
- You will not attack them.
- They will be able to beam up stuff from your planets.
This is very similar (but not identical) to offering Mine Level, Combat Level and Planet Level in PHost.
HOST 3.22.036 adds a second level of alliance, named "FF allies". When you offer this level, they will get all the above benefits, plus they will see all the ships you see. This roughly equals offering the Vision Level in PHost. There is no equivalent to PHost's Ship Level in HOST.
