If you are familiar with the SC2 pro gaming scene, you will probably notice that most professional Protoss gamers are currently using the mass Gateway Style against their Terran opponents. Mass Gateway style utilizes the army mix from Gateways such as Zealots, Sentries, High Templar and Archons. The age of Colossus with Robo build has long been forgotten.
Why is Mass Gateway Build preferable?
Before we go any further, let's take a look at why Protoss players are opting for this build instead of Robo openings and Stargate builds.
1. Gateway units are cheap. Thus, it is worth to trade with Terran armies
2. The strength of Upgrades
3. Zealots with armor Upgrade are great Tanks
4. Efficient resource usage where Zealots only requires Minerals and High Templars require mostlly Gas.
5. In fact, Zealot Archons can be easy to micro while being extremely effective
6. Ability to reinforce instantly during late game with multiple Gateways.
Build Order
I try not to stick to a specific build order here. There can be a couple of different openings against Terrans such as 1 Gate expansion with 1 or 2 Gas, 3 Gate expansion and Nexus first. You are free to use any openings you prefer in your online games depending on the map and your choice.
Let's stick to the 3 Gate expansion for this build.
- 3 Gate into Nexus expansion
