## What is SublevelEscape?

`Sublevel Escape` is a first-person shooter set inside a secret underground research facility. As the lone survivor, you must navigate hostile corridors, gather weapons and ammo, find keycards, unlock sealed doors, and fight your way to the exit.

The game keeps the spirit of classic retro FPS gameplay while being designed for iOS touch controls. Use the movement joystick, look/turn gestures, shooting, weapon switching, minimap, aim assist, and the emergency lock-on button to stay in control during fast combat.

Key features:
- A retro-inspired first-person escape campaign
- Level progression with keycards, locked doors, and exit objectives
- Multiple enemy types and weapon types
- Touch-based movement, aiming, and shooting
- HUD with health, armor, ammo, and minimap
- Emergency lock-on button to instantly face the nearest enemy
- Distinct wall, door, and monster visuals for clear readability

`Sublevel Escape` is easy to pick up for short sessions, but the enemy pressure and navigation challenges keep each run engaging.


## Version history (last 5 releases)

This update adds deeper tactical choices and more rewarding replayability.

  - Added a new 10,000-point scoring and grade system with different priorities for each mission type.
