How are gralats made?
There are a various number of ways to earn gralats, for beginners I'd say the easiest is to get a metal detector and collect scrap parts, do the deliveries, or play missions. It'll be hard at first, but it'll get easier to earn more once you have more and get used to it.
Are they easy enough to farm for?
No farming, but I've found that once you stop spending (i.e. you have your head, body, gun(s) of choice, and other misc items (like a robot or two, or a jetpack)), you'll earn money without realising; Often whilst playing you'll kill players with bounties, or you'll win spring/iricia, or you'll destroy the odd alien rambo and earn ~40-100 gralats each time.
Is the game a costly graal?
Any ways to fast track progress? Like dropping $$ for gralats or something?
Yes, you can do those free-gralat-trailer-things (I've never done them so I don't know exactly what they are) and buy packs. You shouldn't need to though, Zone is different to classic, you can have fun while earning gralats.
Is there trading?
Yes. It does cost money though
but only 1 to get a table, and 100 to go through with the trade.
Any tips?
Don't sweat anything. You might be confused at how everything works for the first couple of hours (or 10) but you'll find it's pretty similar to classic.
