Yeah cheers for the mutators TigaSefi, with those on Adam and myself seemed to breeze through the rest of the waves. If I am online tonight drop me an invite and I will join in for another bash.
I will be on tonight so drop me an invite for the 50 fenix horde run or maybe the fenix beasts please
The progress bar will go up slowly on casual because at that level the money only contributes at ~40%. Add in 3 -10%ish mutators and your progress might only go up by 10%, so for every $1000 spent only $100 will be contributed to the fortification progress.
I just got my fortification levels on normal public games, but they seemed to have changed the public games to casual with your banked money going up by +10% each wave.
