I really need to help with the name of this game, I don't think it was super popular however I will try
to describe it to the best of my abilities and how I remember it.
Here it Goes:
It was a multiplayer army vs humanoid alien game.
Both teams had classes Engineers, medics, snipers , riflemen (If I remember correctly)
Both humans and aliens had vehicles to chose from (Cars, Planes/Hovercraft)
the world map was quite large.
If my memory is not wrong, the entire point was to capture points, pushing enemy back to their
base and then destroying the base.
There was a destructible bridge on the army side of the map.
The gameplay in general was battlefield 2 / battlefield 3 likeish
I also remember the medics used defibrilators to revive friendlies.
