Hey no matter where you look around, each multiplayer shooter bets on Battle Royale mode. I'm not saying that the mode is bad by no means, but I just do not like the mode. I prefer to play this classic concept. Two teams on a limited area play against each other. Can anyone recommend shooters where the servers are not empty. Of course, this does not have to be a current shooter. That means games like Fortnite, PUBG, Apex Legends are already excluded.
For the phone, I can recommend Pixelgun 3d (it's a little funnier than the rest and Battle Royale is available, but the game uses other modes)
Rainbow Six victories
Titan case 2
If MOBA may be: Paladins (but personally I think Paladins are just yawning since the Mobilitynerf and simultaneous Damagebuff of the flanks, the Damagebuffs and Tanknerfs of the tanks and the Heilernerfs especially the Nerf of Shatterspielweise (Ying Ying) Paladins is developing in a pure left-mouse-button-hold-boredom! If you still want to have fun, play Evie the only one that is still fun.
