Architect
of the Union
A tower-defense RTS where you stand in the middle of the army instead of just overlooking it. Build the line, command the front, and don't get overrun.

The Union is collapsing. You are the last architect of its defense, standing shoulder to shoulder with your soldiers, holding one frozen position against the dark.
Build the line
Place walls, turrets, and traps. Read the terrain. Spend what little steel you have where the next wave will hit hardest.
Hold the front
Now you're in it. Command squads, plug the breach, and fight in the line yourself. Fall, and the architecture means nothing.
Resource management
Construct buildings to gather food, wood, and metal, the resources your city needs to survive and expand.
Strategic defense
Spend those resources on watchtowers, radar stations, and barricades to protect your city from what is coming.
In the middle of the action
Play as the architect at the heart of the fight. Run between buildings, command your army, and confront enemies head on.
Army recruitment
Allocate resources to recruit and train a diverse army, from infantry to specialized units.
Progressive nights
Defend against intensifying attacks each night, with the difficulty escalating until you clear the level.
Expansive upgrade tree
Dig into a deep upgrade system with new building types and many enhancements for your existing structures.
