I'm thinking at some titles.
My first suggest:
If someone know the FEAR series. FEAR = First Encounter Assault Recon...
We can make a big title with type (letter)...Something like: HAPB = Humans Aliens Planet Battle (you can do this thing if you want a big title)
Also if you want a title just with one word, need something cool. Tremulous name was take from Quake. Well we need something original. We have to think about this.
You guys can suggest more names!
