like writing here will change something. Invite friends, or go on discord and ask there if someone wants to play now. Online depends from time of the day. Like in all games there are hours when online is higher and lower.
yes, at this moment it's standard shooter game. Game is in development and I think it makes sense to make strong base and only then think about adding something "unique".
i have some suggestions to add some guns like flame thrower, water guns, ice launcher and electric guns that u unlock in prestige 1 or 2 idk, but ur right abt the strong base, im also a game developer and i have half af a strong base to my game :) lol.
You don't have Discord? Sounds like a personal problem...
Lots of the community is active on Discord, just take first step to reach out and see if someone wants to play. Also, players # varies a ton throughout the day. Tends to be most active around afternoon-evening European time.
