You want the best Training Ground?

"The Sandbox" should do it for you. All SC2 units, upgrades and buildings are instantly available on a wide open sandy terrain with ramps and bases. Also 45 predefined micro challenges awaiting you. Relatively few buttons grant you a great variety of possibilities.

Play in The Sandbox solo or 1v1 with a friend:

Find hard counters to any unit composition
Test different upgrade variations
Practice new unit compositions against random armies
Micro against a working tactical AI
Outmicro mirror armies
Hold ramps of all kinds
Plan your base build
Defend your mineral line
Practice drops
Play predefined micro challenges
Invent your own challenges

You are not in the mood for competitive starcraft? Go play in The Sandbox, explore and improve.

What is better in The Sandbox?

I know, there are some good Unit Tester and Micro Trainer around, but "The Sandbox" is the next step in the evolution of the training grounds, I think.

The terrain has some real base locations with natural expansions (extracted from actual ladder maps).
You can display not just the army cost, but also the upgrades cost and the buildings cost.
You can build anything instantly with tool units or like usual (build a worker...)
I put a lot of work in the random armies, so you just press the random button and have fun.
The tactical AI uses abilities and is not too bad.
You can create and save your own challenges.
And I hope you like the style.
