The Gate is a defensive building that blocks passages at designated locations on the map.
| Health | 800 |
| Building limit | 4 |
Upgrades
Armor I
Armor I increases the Gate’s maximum health by 50% and fully repairs all existing damage.
Armor II
Armor II increases the Gate’s maximum health by 100% of its base value and fully repairs all existing damage.
What is the Gate?
Gates turn map geometry into part of the defense. They deal no damage, but close a convenient route, force a ground army to stop, and give defenders time to take a favorable position. Properly placed Gates reshape the battle itself: the opponent must assault a prepared approach instead of bypassing the army and suddenly reaching the economy.
Strengths
- 800 health for 5 ore — no other building gives you this much durability at that price.
- A single Gate blocks a passage completely: it spans a strip of 8 tiles, so you do not need a second building on the same approach.
- It requires no other buildings — you can start a Gate in the very first minute of the battle.
- Armor I and Armor II cheaply raise durability to 1200 and 1600 health, and completing an upgrade fully restores the building.
Weaknesses
- It does not attack: the Gate is only a barrier, and without an army nearby it merely buys time.
- It can be built only at designated spots on the map—in front of ramps and at bridge connections. A Gate cannot be placed in the middle of an open field.
- It does not stop aircraft: the Thunder, Hawk, and Balloon fly over a closed Gate. A Turret and anti-air units can stop aircraft from bypassing the Gate.
- An open Gate lets everyone through, including the enemy army, so the doors must be controlled manually.
- Tanks with their double damage to buildings destroy even an upgraded Gate very quickly.
Passage control
The best Gate locations are ramps and bridge connections where the enemy cannot simply drive around the obstacle. A closed passage protects the harvesting line and reveals the direction of an attack in advance. To let your army through, open the Gate manually and close it again right behind it.
Gates and the army
The Gate delays Lynxes and gives the Devastator time to fire from a safe distance. A slow Titan can finish production and join the defense. A Worker can repair the Gate during battle, while an Armor upgrade started in advance fully restores its health when completed.
Opening and closing the Gate
The Gate is the only building you control during battle. A closed Gate occupies terrain tiles and lets no ground unit through. An open one clears the passage, but for everyone at once: both your army and the enemy army will pass through an open Gate.
Use the button on the Gate itself to open or close it. The doors take about a second to move, and the Gate cannot be toggled again while the animation plays—if the enemy is near, do not put off closing it.
How do you get past an enemy Gate?
An enemy Gate in your path is no reason to turn around. There are several ways to get through:
- Go around by air. The Gate blocks only ground units: a Thunder hits the defenders and the economy from above, while a Hawk covers it from enemy aircraft.
- Carry troops past it by air. The Balloon carries Tanks, Lynxes, and infantry past the Gate; recommended troop combinations are covered on the Balloon page.
- Break through with Tanks. The Tank deals double damage to buildings and destroys even an upgraded 1600-health Gate quickly. Only the Titan can match that speed, and the Tank is considerably cheaper.
- Do not allow repairs. Enemy Workers can repair the Gate during the assault—drive off or kill the repair crew first, or your damage will go to waste.
Early Gate construction
Construction sequence
One possible construction sequence for defending against an early Lynx breakthrough:
- After producing the fifth Worker, start building a Gate but do not complete it yet.
- As soon as you have 10 ore, build a Reactor.
- Send the Worker who completed the Reactor to finish the Gate.
- Use another harvesting Worker to build a Barracks and continue producing new Workers.
- After the Gate is complete, send the free Worker to build a Factory, then continue with the chosen plan.
This construction sequence slightly delays standard development but strengthens defense against an early ground attack.
Tips
- Armor as an emergency repair. If the Gate is about to fall under fire, start Armor I: 6 ore and 15 seconds of research are a small price to keep the approach closed and raise durability to 1200. The same technique works with Armor II.
- Repair instead of rebuilding. Send a Worker to the damaged Gate, and the Worker will begin repairs automatically. Unlike new construction, repairs cost no ore.
- Demolish a Gate only when necessary. Demolition is useful when an approach no longer matters and the four-Gate limit prevents you from building at a new location. The free 20-second demolition frees one slot under the four-Gate limit.
Where can you build a Gate?
Only at designated spots on the map—in front of ramps and at bridge connections. A Gate cannot be placed in the middle of a flat field. A single Gate covers a strip of 8 tiles and blocks a passage completely.
Does the Gate stop aircraft?
No. A closed Gate blocks only ground units — the Thunder, Hawk, and Balloon fly over it. Against air attacks you need a Turret and anti-air units.
