Moduwar is an adaptive organic RTS where you control an alien creature, it's quite unique and looks really interesting.
More about it: "Moduwar is a Real-Time Strategy game that redefines the genre with its unique modular gameplay. Instead of commanding traditional units, you control the Modu, a highly adaptable native species of water-dwelling creature capable of growing, merging, and splitting their organic structures in real time. By strategically evolving different organs, you create custom units that adapt to any battle scenario."

It entered Early Access in June 2025, and came with a Native Linux version. However, it's taken them until October 8th to fix a really annoying problem with it. The Linux version had a hilariously oversized cursor, a problem I see a fair bit in Unity games. Nice to finally see it solved. Shame it took far too long to solve such a bug though.
