The absolute classic that is Soldat, which went fully open source back in 2020 is now in need of someone to take over as the original creator has announced.
"Soldat is an exciting unique side-view multiplayer action game. Played by hundreds of players at this moment. It takes the best from games like Liero, Worms, Quake and Counter-Strike and gives you fast action gameplay with tons of blood and flesh. Little ragdoll soldiers fight against each other on 2D battle arenas using a deadly military arsenal. This is what multiplayer was invented for."
Creator Michał "MM" Marcinkowski announced the news via Twitter. It's not surprising, as keeping up an open source project, especially for a full game like this, can be very time consuming. MM has also been working on Soldat 2, so their time is likely quite limited.
