Tips & Strategy
Excelling in Core Defense means mastering threat prioritization and maintaining constant vigilance across the entire 360-degree attack radius. Your central turret is your only defense, so make every shot count. Always be sweeping your mouse to check for new enemies approaching from any direction, not just the front. Faster-moving enemies or those already close to your core should be your top priority, as they pose the most immediate danger.
When dealing with multiple threats, quickly eliminate groups of weaker foes to prevent them from overwhelming your defenses. For moving targets, try to "lead" your shots slightly by aiming a bit ahead of their current position to account for projectile travel time. This ensures your shots connect more reliably. Don't get fixated on a single enemy; if a more critical threat emerges elsewhere, switch targets immediately. Effective defense relies on quick target assessment and decisive action.
