A less painfully long way to get euro's is the Bg maps--difficulty and some fprm of gambling with time has a factor-- because you have to earn 4-4.5k euro's an hour to make it worthwhile compared to 3 box farming4.5k an hour max rate--where i got 11k in an hour on BG(6k really- but got supply lumpsomes of 2-5k as well,which gave me a supply up, plus more). My record in an hour is 17k euro in BG-- but luck can be a pain still, where you get no euro's, just exp and zonda bats :/ pike is good tho and beretta.
A good round let's me buy ammo for pvp, armor or at least try to get EA08 from the capsule(still wanting my first capsule gun <3)
The ability to earn a timed/ perm beretta is worth the investment i'd say if you can't get a walther from 10-12 box or don't like the glocks iffy accuracy. We can't buy a perm beretta(for euro only players, but could buy perm with gcoin or ap from past events), but we can at least earn one. So that's something at least. If only the extra beretta's we're worth something--starting to fill up on permanent berettas XD (i should make one of mine 0% at least).
Lockdown does give you armor at least, 08 gear and 07--ussualy helmet. get it more than euro's at least if i finish.
