Either grind or pay

I used to think this game was pay to win because of the difficulty of collecting blueprints how you unlock new weapons and stuff are dropped by Mini boss zombies which do not spawn all to much but be prepared to grind for blueprints or pay money anyway how I grind blueprints is mission (seek and destroy) destroy all the loudspeakers/radios except one then with 1 left go away from it to about 50% on your meter then return to the speaker killing all the zombies that followed you while making your way to the final speaker once u get close enough a boss zombie should spawn soon rinse and repeat keep in mind blueprint drops are rare and it will take awhile also dont rush ur tech collect all the current tech blueprints then upgrade it
