NECR: Chain Reaction Physics is a 2D physics-based skill game focused on one-shot mechanics and chain reactions. The player launches a single core to interact with enemies and environmental objects. Collisions, explosions, and physics interactions create chain reactions that determine the final score. The game emphasizes precision, timing, and player skill. There are no upgrades or pay-to-win mechanics. Features include multiple enemy types, interactive elements such as bombs and teleports, and a global leaderboard for score competition.
