You had around 13-14k "new" players playing your game when you released it on steam, where are they now? Do you think new players are interested in outdated game engine, with breaking game bugs like right peeking which never got fixed and destroys pvp in 3rd person view (just one example). Do you think new people will install this game and say "oh what a nice game, I'm really enjoying this!" ?
This is my perspective on things. A new player joins an open world server, gets sniped in the face in the first 20 to 30 minutes, he tries again and this time a clan of 10 jumps on him. He gets pissed, goes to pvp servers, same thing, gets crushed in seconds. Turns off the game, tries again next day. Starts the game, goes to battle royale, waits 30 minutes for a match to start just to die in the next 2 minutes. What's left to try? Survival? Joins a random server, gets enough loot to pvp and then goes to the only full server there is which has 3 to 10 people groups camping major cities/places. Do you think that new player will have fun and keep playing this game for much longer?
At least you'd have more people playing the game if it was what it used to be + cheater free, which was a dream back then.
To get new people to play your game you'd have to make it enjoyable and fair for them, which is a very hard task in newz. Becuase of its player base, too small to make good changes such as ranking (like in csgo), silvers would play with silvers, globals vs globals and when new players get better at the game they auto rank up and end up playing with the rest of good players. There's good options to soften new player's first times playing this game, but requiers larger player base.
Other thing I want to point out, have you thought about hiring a professional designer instead making skins and items yourself and your current team? I've seen so much creativity in iss community, it's amazing the things people do, yet you guys design boring/bland skins and items which don't really look good, no offence. And yet, you charge a ton of $ for them. It's not a complain, just a suggestion. I'm pretty sure players would appreciate and perhaps spend more $ than they did until now.
Anyways, these are my thoughs. No hate, I want this game to succeed at some point in time. Peace.
