-Any and all attempts to contact the invading Martian forces have been either ignored or met with violence. It is obvious that they have no desire to co-exist with Humanity. The Martians present the largest danger to continued Human existence due to their proximity to Earth and their extreme violent behavior and seeming desire to exterminate us. For whatever reason they have not invaded us in full force. (Possibly due to us having non human allies or possibly due to the lack of resources on their own homeworld to invade Earth.
Most of their tactics include attemping to destroy dams, overload power stations and sow anarchy. As well as simply wiping out entire towns with their lethal Death Rays. Take prisoners only if possible, otherwise eliminate with extreme prejudice.
While normally these creatures are not actively hostile, these aliens can be sometimes (especially if they are feral and accustomed to living in the wild) and have jeapordized the safety of agents out in the field. They are known as Gremlins by us though they have no name for their own species. According to our allies they are bassicaly the vermin of the universe, getting into everything and causing damage. It is not even known how they managed to get on Earth without space travel technology of their own. Their mischievous nature presents the greatest difficulty in attempting to keep our war a secret as they do not seem to care about being seen by others.
They oddly enough seem to enjoy cigarettes, alcohol, gambling, as well as other vices. Thus some of them have elected to work for us/do sabotage work int he field against the Martians. Though don't put full faith in them to actually do their job 100% and those in the field not working for us may be feral and turn violent. At the very least they attack the other races as much as they attack us, having no real preference for factions.-Balal
The Balal's are the newest alien race spotted trying to invade the planet Earth. Thus little is known about them. First spotted outside of Seoul South Korea by local agents there, they have since been seen in Moscow, Mexico city and Nevada. We don't know what their goals are but they have not responded to any attempts at peace talks, so treat them at hostile.
The most secretive of our enemies is the Reptilians. They seem to want to rule over Earth and Humanity rather than destroy one of the other. Many times a Reptilian can be found infiltrating or attempting to infiltrate into high ranks of power. It is unknown how they do this but we do know that the process is imperfect. They cannot grow hair, alter their eyes or hide scales on every part of their body, they also do not handle colder temperatures well.
Attempt to capture if possible but be wary, they are very well trained and organized.
