I was thinking about global events that could happen in the game. And sure at first I thought about things like massive raids and epic boss fights. But when I thought bigger and something odd happened, there would be things that both the Humans and aliens would see as common threat and seek to stop or at the least minimize the effects of. Even if they are not talking to each other or made any kind of deal with one another they can recognize what the other is doing and not hinder it. This would also mean that even those they are at work with each other there are some places they would not attack if they can avoid it because what is being done there helps them just as much as it helps of the enemy.
For example, least say there is massive cosmic storm heading for Em-8er. One powerful enough that it could damage the atmosphere enough to a threat all life on the planet, if it does not completely destroy the atmosphere. There is some warning time so the Humans start to build things to help protect the planet from the storm. Likewise so does the aliens. Because both sides are smart enough to know what the other is building and why, they are also smart enough avoid attacking those things even while fighting.
So I was thinking what are some things you could think of that would make the humans and aliens have an unspoken truce about some things?
The only things I'm able to come up with for the time being are things like a nearby star going nova, a high radiation cosmic storm, a rogue planet or moon coming into the system (rogue planets and moons are ones what no longer orbit a star because they kicked out of there home system by larger planets or the star(s) died. A lot of drift out in the space between stars and galaxies.), shock waves from a starquake of things like neutron star or magnetar, or having a portal/rift grow to big and powerful going out of control while making spacetime on and around the planet to become unstable.
