A roundup of four Humble Bundle deals relevant to game developers. Two new bundles feature Synty (Cinti) low-poly stylized assets with a sci-fi theme, including a Sci-Fi City/Space pack compatible with Unreal Engine, Unity, and Godot via FBX, priced at $30 flat. A second new bundle, the Ultimate Survivor Kit Redux, offers realistic military vehicles, environments, and characters for Unreal Engine. Two ongoing bundles are also highlighted: a 3D artist tools kit with hard-surface sculpting and modeling assets, and an Extreme Gamedev environment bundle supporting Unreal, Unity, and Godot.
