About the Orc Defense

Mumpitz Games built this single-player tower defense game around a simple but demanding loop: place defenses, start the battle, survive the horde, and spend the reward. The incremental-style upgrade tree keeps failed attempts useful, while turrets and active abilities give each route a different defensive problem. Bullets, bombs, lasers, and a manual missile let you respond to pressure in different ways. Strafing runs cover a route, orbital lasers punish enemies that stay in line, and nukes provide an emergency burst when the crowd reaches a dangerous point. The Steam release supports Windows, SteamOS, and Linux.
How to Play the Orc Defense
Controls
Space: Start the battle Left click: Fire the manual missile Mouse position: Aim the manual missile
Choose a stage, place your turrets, and aim them through every visible route before pressing Space. When one path begins to leak, use the mouse to guide the manual missile toward the first dangerous group. Resources from every run, whether won or lost, unlock and upgrade turrets. The opening stage contains 400 orcs, while later stages scale into much larger crowds, so replaying a cleared stage can be the fastest way to strengthen the next defense. Save strafing runs, orbital lasers, and nukes for dense groups or a late breakthrough. A permanent coverage problem needs a better layout, but a short-lived leak can often be solved by direct missile fire or a well-timed ability.
