The battle wasn't going well for either side.
Both sides kept learning and adapting to each other. Hundreds of mechs and fish-whales began to run low on reserves and started to accumulate damage. Once they exhibited obvious weaknesses, their opponents did not miss the opportunity to finish the job!
As casualties kept mounting for both sides, the mech pilots attempting to contribute to the battle in their own way experienced greater and greater difficulties.
The Phasers started to recognize the threat posed by the small and odd-looking metal machines.
While they weren't as clear of an enemy as the Evolvers, the mechs had an annoying tendency to hit the Phasers where they were weak!
This caused plenty of them to suffer crippling injuries, which eventually led to their downfall!
