Today I have overhauled how the Endurance mode worked.
As you progress through the 100 waves the difficulty of the game increases. At Wave 100 you will be getting hit 10 times harder than you did at Wave 1.
That's the stick. Here is the carrot.
To counter this, as you move through the waves, a constantly increasing score multiplier will run alongside this difficulty ramp. At Wave 100 you will be scoring 10 times the points you were at Wave 1.
So, the mode quickly gets a lot harder, but the points you can score in those higher Waves is HUGE.
Happy blasting.
