About Planet Defense
The universe is a vast and uncharted territory, but now it faces a grave threat. Welcome to Planet Defense, where your home planet is under siege by a colossal asteroid. Powerless against the enormity of this celestial intruder, it falls upon you to safeguard your world. Your mission is to deploy advanced weaponry and strategize your defenses to obliterate the
The genre lives on enemies with distinct behaviours, precise aiming and waves or levels that build up. Planet Defense understands that, and it shows in the first minute of play. Playing it works your target prioritisation and resource management, which is a large part of why the "one more round" feeling is so strong.

Tips and tricks
- Move between shots. Many shooters make you an easy target only when you stand in one place.
- Sound tells you where an enemy is before you can see it. Headphones help more than you would expect.
- If there is a reload, reload during quiet moments — never in the middle of a wave.
- Learn the spawn points. Most levels reuse the same few entry points, and knowing them turns panic into routine.
- Because this is a Action game, keep moving.
