Aegis Line

Aegis Line is a casual tower defense game. English Version — How to Play ### Goal Enemies march along the armored road from the entry point toward your forward base. Deploy weapon turrets on the **empty ground beside the road** to stop and destroy them. Every enemy that reaches the command bunker gate costs you lives; **when lives hit zero, you lose**. Survive all waves to clear the level. ### Core Resources - **Gold**: Used to build and upgrade towers. You start with 200 gold, earn more by killing enemies, and passively regain +1 gold every 6 seconds during non-boss waves. - **Lives**: Start at 20 (scaled by difficulty). Each leaked enemy reduces lives; zero lives means defeat. - **Medals**: A persistent cross-level currency earned by playing, spent in the main menu to unlock permanent upgrades. ### Towers (4 types · the Four Weapon Turrets) | Tower | Cost | Trait | |-------|------|-------| | Autocannon Turret | $50 | Single-target, fast attack, best all-round starter | | Cryo Turret | $55 | Slows enemies on hit, lower damage, for crowd control | | Pulse Turret | $75 | Attack pierces up to 3 enemies at once, long range | | Artillery Battery | $90 | Area splash (AoE) damage, high per-hit damage, slow fire rate | ### Tower Upgrades Each tower can be upgraded to **level 5**, with 5 upgrade paths: 1. **Armor**: Ignore/reduce enemy armor 2. **Damage**: Increase attack power 3. **Attack Speed**: Shorten attack interval 4. **Range**: Extend attack range 5. **Special**: Enhance the signature effect (pierce count, slow strength, splash radius…) Upgrade cost scales with level. At **level 5** you can enable the tower's "auto-cast special". Tap a placed tower to open its info panel and **upgrade** or **sell** it (selling refunds 80% of cost). ### Skills (cast free by watching a rewarded video) - **Orbital Strike**: Deal 50 damage to all enemies on the field - **Cryo Field**: Slow all enemies by 70% for 3 seconds - **Tactical Supply**: Immediately gain 50 gold ### Enemy Types Assault Mech, Raider Mech, Heavy Tank, Annihilator (Boss), Recon Flyer (ignores slow and some effects), Support Bot (heals nearby enemies), Suicide Bot (explodes on death), Regenerator (heals over time), Splitter Swarm (splits on death), Bulwark Mech (shield absorbs damage). ### Difficulty - **Easy**: enemy speed ×1.0, lives ×0.6 - **Normal**: enemy speed ×1.4, lives ×1.0 - **Hard**: enemy speed ×1.8, lives ×1.5 ### Controls 1. Tap a tower in the bottom build bar to enter placement mode (green ring = valid / red ring = invalid). 2. Tap empty ground beside the path to place it; press **ESC or right-click** to cancel. 3. Tap a placed tower → upgrade / sell. 4. Tap a skill button (after watching an ad) to cast the skill. 5. Use the pause button anytime. On defeat you can retry or return to the menu from the results screen; clearing a level unlocks the next one. 6. **Drag up/down on the battlefield to pan the view** and check path segments hidden behind the bottom bar; taps still select/place towers (drag and tap are distinguished automatically, works with touch on mobile).
