Rush¶
Pure reaction mode. The player is locked to the Assault Rifle with infinite ammo. No bonuses, no perks, no pickups. Score is survival time.
Starting conditions¶
- Weapon: Assault Rifle (forced). Cannot be changed.
- Ammo is refilled to full clip every frame.
- Bonuses: disabled.
- Perks: disabled.
Spawning¶
Every 250 ms, two creatures spawn simultaneously:
- Right edge: Alien (type 2).
- Left edge: Spider (type 3), 1.4× faster than the right-side alien.
Both spawn positions oscillate vertically using sine/cosine of elapsed time.
Spawn cooldown decreases by player_count × frame_dt, so multiplayer
speeds up the pace.
Scaling over time¶
All creatures scale with elapsed time:
| Stat | Formula |
|---|---|
| Health | 10 + elapsed_ms × 0.0001 |
| Size | 47 + elapsed_ms × 0.00001 |
| Move speed (right) | 2.5 + elapsed_ms × 0.00001 |
| Move speed (left) | right speed × 1.4 |
| Contact damage | 4.0 (fixed) |
Scoring¶
Ranked by longest survival time. The end-of-run record includes kills.
Game over¶
The run ends when all players are dead.
