Boom Castle · Tower Defense

Orcs at the gate. Decisions to make.

Boom Castle is a fantasy tower defense game where you choose random upgrade cards between waves, and build synergies across heroes, gear, gems, and traps. Defend through five acts – orcs, undead, demons, dark elves, void – each with enemy resistances your build needs to answer. Many heroes, castle wall progression, idle farming, and endgame gem builds that keep strategy evolving across 400+ levels.

We started from scratch in 2022 because we wanted full ownership over our creative decisions – and that hasn’t changed.

No crunch, no toxic politics. Everyone has a real say in where the company and our games are heading. Meetings are open to anyone, information is shared by default, and you’re never left wondering what’s going on.

We keep a zero-bullshit culture where every voice matters, and we intentionally built an office that’s friendly to dogs, kids, and friends alike.

At Terahype, our goal is simple – hire experienced people with a proven track record in the gaming industry who can help move the company forward fast. We look for high agency people – people with drive, ownership, and the ability to solve problems instead of waiting for someone else to do it. We’re building a team of partners we’d genuinely want to co-own Terahype with one day and share the success together. That’s also why we actively support and implement our ESOP plan.

Together, our team has spent 150+ years in the gaming industry, including more than 100 years in mobile games alone. Our team members have worked on legendary titles such as Hidden & Dangerous, Vietcong, Mafia, Need for Speed, Shadowgun Legends, Dead Trigger, TrainStation 2, Gray Zone Warfare, Smashing Four, Port City, and many more.
