Last Run: Survial Fight

"Core Gameplay Flow Pre-Mission Prep: At the start of each stage, review your current Troop Count, Gold Coins, and the two doors ahead—each clearly labeled with a troop modifier (e.g., “+X” or “–X”). Shop & Upgrades (Pre-Combat): Spend your Gold Coins freely in the shop to upgrade your squad: Upgrade Weapons: Permanently increases each soldier's base damage. Recruit Soldiers: Instantly adds new soldiers to your squad. Purchase Combat Boost: Grants a temporary damage increase for the upcoming battle only. (Note: You can purchase multiple upgrades simultaneously as long as you have enough Gold.) Choose Your Path: Select and pass through one of the two doors. Your Troop Count is immediately adjusted based on the door's label (e.g., Troops: 15 → 18). Automatic Combat: Your squad automatically engages and fires at alien enemies within the corridor. Enemy return fire will cause random troop losses during the battle."
