Decoding the All-In Attack
An early aggressive rush is designed to end the game before you can even establish an economy. If the attacker cannot break your lines quickly, they will inevitably lose the long game. If you do not know the rush is coming, you will undoubtedly be crushed. Stay calm, stick to your defensive protocols, and trust your static defenses. We will cover the specific techniques required to hold the line against these aggressive tactics.
Bunkering Down
Stop producing economic workers and immediately dump all resources into military units. Forcing the enemy to walk through a narrow gap drastically reduces their damage output. Towers deal high, consistent damage and cannot be easily focus-fired by early units. Do not engage the enemy army in the open field under any circumstances. This is a last-resort tactic, as it completely destroys your economy.

Assign a few workers to constantly heal the buildings forming your defensive wall. Never give up the high ground to chase a retreating enemy. Killing the enemy leader will often break the morale of the attack and force a retreat. Proxy barracks cut down the enemy's reinforcement travel time to zero. The enemy might be baiting you into a trap or preparing a second, stronger wave.

Specialized Defenses
Scouting is critical to determine exactly what kind of aggression you are facing. A well-placed incendiary trap can wipe out fifty cheap units instantly. Invest in magic towers or snipers that deal high single-target burst damage. Sometimes, the enemy will execute a 'tower rush,' building offensive turrets near your base.

Hidden BarracksEnemy main base is empty; no barracks found at their spawn.Scout the perimeter of your own base; destroy the hidden buildings quickly. Early Boss RushEnemy rushes to a tier-two structure immediately; low unit count.Build armor-piercing magic towers; use slowing effects to kite the heavy units. The Tower RushAn enemy worker is seen lingering aggressively near your natural expansion.Pull 5-6 workers to kill the enemy builder immediately before the structure finishes.

When you survive the rush, the rest of the game is usually an easy cleanup. Do not get frustrated if you lose to cheesy strategies while you are learning. You will not have time to figure out the geometry during an actual panic situation. Remember that the psychological damage of a failed rush is immense for the attacker. Hold the line, protect your workers, and secure your inevitable victory.</p
