1) Buy weapons in this order: Revolver> M67> Carbine> Whatever you want
2) Don't sell weapons. Ever. It's literally wasting your time and *****.
3) Don't buy upgrades. They're not valuable enough to use in the early game, it's mostly for people who have everything that they need already.
Here's my boring tip as a bonus: play on small maps that promote close quarters combat like Snow War to get back in action faster. Lob M67 and you'll likely score some kills randomly considering how packed that particular map is.
*Edit: Ah yes, or get trap mines and scatter them around choke points like the Armoury. Easy kills.
The most logical and worst tip at the same time is: git gud. How much you earn is directly correlated with how efficiently can you slaughter people using even starter gear.
Spacetrooper said:OR selling weapons can give you the amount that you bought it for (100%) becuase 70% is a big difference.
why should it be 100%
you can't do that because you might have already used it or smth, then returning with same price?
I think it should be 80-85 % because 70 is different yes.
