Idea for a new Co Op map

In the wings of liberty campaign there is a mission that you invade char and dominion forces get pushed back hard and most of them die in the invading phase and the main obj is to save as many dominion forces as you can and ultimately rescue general warfield now there can be a triangular map that both players start in the both bottom corners of the map (start speratly from each other) to investigate an abnormal activity from the feral zerg that try to make a new overmind by the order of Amon and you have to fight your way through waves of zerg and destroy it (there are going to be 3 falling battlecruisers like general warfield’s that you have to rescue as bonus objective)
now in order to destroy the new overmind you have to destroy 5 cerebrates then attack the overmind
ofc this mission takes place in char with millions of zergs so there are going to be countless waves of zerg and if your base gets overrunned with zerg you wont lose the game
btw this is just an idea that came to me so dont be too harsh i couldnt bare not to share it

Only one enemy race. Too easy to counter (like it’s not already too easy). Would become boring really fast.

Please see description for new 4th race
