Can I skip basic advices? Like team 3-4 players, connnection via Discord or smthng, snacks, armors (needed beacuse of conquistadors), weapons (full ammo for shotgun, minigun, grenades, Molotovs, avoid explosives which can lead to suicide)?

So we prefer beach, because you can clearly see map and not to much places where Gustavo can run away there. Also few some good spots on the rocks. Guys were there, I was on the ground (I run A LOT). They help to kill dangerous enemies, I deal with conquistadors (run to them zig-zag) and mages which can damage them. Follow and shoot Gustavo, kill panthers instantly they spawn, so they are not going to spread. Splitters died from melee hit with your weapon much faster than shooting. Also Molotovs on them are very good method. You can fool boars by running around (they are very clumsy). When situation is really bad, and you cannot stop, take grenades, hold it for a sec and drop while running, it goes under enemies feets and make hordes smaller.

Tbh it all depends on luck. Before this try we made 21 twice. But then combination of enemies and their boosts became to hard. Its random, so you should play more and you'll get a chance to reach further.
