Read the mission.
Open Campaign, choose a mission, and read its waves and goals before you deploy.
Place your towers.
Choose a tower, tap a compatible pad, and check your credits and available power.
Start the wave.
Let construction finish, then start the wave. Healthy deliveries earn credits for more equipment.
Repair and research.
Repair between waves. Earn research points from mission objectives and unlock new equipment.

First mission: Follow the highlights. Add a second Quick near the exit, then a third before wave 2. Pausing also pauses construction.

Equipment reference 10 tower families, 3 generations

How we built Rush Hour

An EVOCS hackathon project.

We spent a week-long hackathon at EVOCS building a game about overloaded networks. Apparently, we needed a hobby that also involved capacity planning.

We built Rush Hour using Vox, our AI development harness, putting different models to work on planning, code, and artwork. Each asset got individual attention, followed by plenty of playtesting and fixing things.

One of our teammates is also composing an original soundtrack with synthesizers. We have very strong opinions about music, so this was always going to become somebody’s side quest.

We made this for the moments between sessions, meetings, or another round of checking your inbox. Build a few towers. Keep the packets moving. Try not to cook the equipment.
