This build is a gimmicky all-in that builds a Factory near your opponent’s base and then starts proxy Widow Mine production before your opponent can possibly have detection out. This build is designed to devastate your opponent’s economy before they even reach the midgame.
- 10 – Supply Depot
- 12 – Refinery
- 13 – Barracks
- Send SCV out to build proxied Factory
- 17 – @100% Barracks, start Factory at proxy location and Orbital Command
- Start constant Marine production
- 18 – Supply Depot
- 22 – @100% Factory, start Widow Mine production
- Send constant Widow Mines at your opponent starting when your first Widow Mine finishes (@4:40ish). You should have 3 Marines and 19 SCVs at home.
This build is only viable on 2-person spawn maps, so you do not need to SCV scout in order to figure out where your opponent is spawned. Therefore, there is no scouting at all done – you will proxy the Factory and send in the Widow Mines regardless of what your opponent has been doing.
Once you have Widow Mines in your opponent’s base, you should be able to scout exactly what sort of tech they will use to get detection – Oracle or Observer. Use this knowledge when you are transitioning into the midgame to get a leg up on your opponent.
This Proxy Widow Mine build does not have a clearly defined follow-up because of how differently each game plays out. However, it is usually a good idea to start a Reactor on your Barracks at home as soon as you feel safe in order to save minerals and eventually get a 2nd Command Center. Then you can transition into normal Bio or Mech play by adding on the extra infrastructure and Refineries you need for a delayed, but normal-looking midgame – using your few Marines and a Bunker for defense against any counter all-ins your opponent might try on you.
Alternatively, you can continue the all-in yourself by adding on more Barracks on 1 base and getting a Tech lab on your first Barracks. Start Stimpack Research and Marauder production and go for a Bio/Mine 1 base Stimpack all-in with all of your SCVs.
Pros and Cons
Getting such fast proxy Widow Mines disrupts your opponent’s early game plan by killing lots of Probes before your opponent even has detection.
However, it is a gimmicky build because it relies on your opponent either being out of position or delaying their detection. If your opponent defends without losing too many Probes, then their tech and economy will most likely be ahead of yours going into the midgame.
This build is only viable on 2-person spawn maps so that you can proxy the Factory without having to scout where your opponent has spawned.
