## What is PROTOCOL?

The day dimensional rifts opened, 
monsters and the Dimension Awakened appeared at the same time.

As monsters spread across the world, the government gathered students with dimensional powers and established the Tactical Academy. 
Become its commander, train your students, and deploy to a city under threat.

Control the leader directly and give orders to two fellow agents. 
Combine their abilities, weapons, and parts to lead a three-person squad.

• Survive the waves of monsters.  
• Train distinctive students and build your squad.  
• Find powerful combinations, overcome each battle, and protect the city.

A two-person indie game.
