Game info

Game Introduction

Space Duel: Cosmic Energy Clash is a fast-paced two-player space duel arcade game. Set in a retro science fiction universe, it pits two cosmic beings against each other in a side-scrolling arena. The core objective is to reduce your opponent's energy by hitting them with energy attacks while using shields and energy charges to outmaneuver and outlast them. Designed for local multiplayer on a single keyboard, it offers quick, intense matches that are easy to pick up but provide enough strategic depth to keep players engaged. The space theme and side-scrolling perspective create a classic arcade feel, making it ideal for short gaming sessions or friendly competitions.

How to Play

Two players share one keyboard. Player 1 typically uses the WASD keys to move, with additional keys for stabilizing, charging, shielding, and firing the energy attack. Player 2 uses the arrow keys for movement and other designated keys for their actions. The goal is to deplete your opponent's energy by landing energy hits. You can block incoming attacks with your shield and charge your energy attack for more powerful strikes. Stabilizing helps improve your aim. The first player to run out of energy loses. Quick reflexes and smart resource management are key to victory.
