So how costly is waging war on one another? After my first serious battle, dealing > 130k damage, it looks as follows (all according to current, displayed market values):
Sniper rifle used in 86%:
90*0,86 = 77,4
Equipment (blue) used in 67%:
(14+16+15+19+20)*0,67 = 56,28
Heavy ammo x86:
86*1,58 = 135,88
Pill:
14,28
Cooked Fish:
11*3,31 = 36,41
All in total: 320,25
It is expensive, even when not at a top level. It would take 64 people tipping this article to break even.
Was it worth it though? Totally :)
