Rift Arena

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Create a browser-playable local 2-player survival arena game titled “Rift Arena,” using a dark neon sci-fi 3D presentation. Show a top-down/angled third-person camera over a circular arena with a dark blue-black cylindrical floor, a subtle square grid, a glowing metallic blue perimeter ring, and evenly spaced short futuristic pillars around the outside. Use soft atmospheric fog, shadows, cool blue lighting, and a nearly black background.

Place two glowing capsule-like player characters in the arena: Player 1 is bright mint/green and starts on the left, while Player 2 is bright blue and starts on the right. Each has a luminous white-centered core and a soft ground shadow. The camera should follow the midpoint of the two players slightly while keeping the full arena action visible.

This is couch co-op survival: Player 1 moves with WASD and Player 2 moves with the Arrow keys. Movement is normalized for diagonal input, has damped stopping, and is constrained inside the circular arena. Both players automatically fire at the nearest hostile enemy; there is no manual shooting or aiming control. Fire small glowing projectiles in the player’s color toward the nearest enemy at regular intervals. Projectiles damage enemies and disappear on impact or after a short lifetime.

Spawn hostile drones around the arena edge. Enemies are small hovering orange/red octahedron-shaped drones with emissive coloring, spinning and bobbing as they chase the nearest living player. Begin at Wave 1 with an enemy goal of 6, spawning enemies over time up to that goal. Each enemy has health, becomes harder and faster as waves increase, and damages players by contact with a cooldown, knocking them back. When all enemies are cleared, wait briefly, advance the wave, increase the wave goal (capped at 24), and restore 10 health to living players. Continue spawning progressively faster and tougher enemies.

Occasionally spawn floating rotating/bobbing pickups inside the arena, with at most two active at once and a limited lifetime. Green pickups are heals and restore 25 health; yellow pickups are speed boosts and increase movement speed, capped at 11.5. Collecting either awards 5 score. Killing an enemy awards 10 score to the player whose auto-fired bullet dealt the finishing hit. Each player starts with 100 health and displays Alive/Down status. A player at zero health is down and disappears; only living players can move, shoot, collect pickups, or be targeted. When both players are down, end the game and announce “Player 1 wins,” “Player 2 wins,” or “Draw” based on their scores.

Add a fixed translucent glass-like HUD overlay with thin blue-gray borders, rounded corners, blur, and white text. Put a Player 1 panel at upper left showing PLAYER 1, “Score 0 · Alive” initially, a mint health bar, and “WASD move.” Put a matching right-aligned Player 2 panel at upper right showing score/status, a blue health bar, and “Arrow keys move.” Center a top panel showing “Wave 1,” “Enemies 0/6,” and “P1 auto-fires · P2 auto-fires.”

At startup, show a large centered translucent banner reading “Rift Arena,” “Local 2-player survival — press Space to start,” and “Space to start · R to restart.” Press Space to begin and hide the banner. Press R at any time to reset the arena, wave, scores, health, players, enemies, pickups, and timers to the initial state. On game over, show the centered banner with “Game Over” and the winner plus both scores. Keep the visual style polished, minimal, neon, and readable, with no invented weapons, enemy types, bosses, networking, split-screen, or manual fire controls.
