Curator review

Get ready to fight unrelenting waves of enemies in TETRAGUN! Choose your upgrades wisely and adapt to randomized runs to survive.

Full review

TETRAGUN takes the classic turret defense concept and adds an exciting twist. In this game, you find yourself in a constant battle against waves of enemies, with your trusty turret as your only line of defense.

What sets TETRAGUN apart from other games in its genre is the quadrant-based gameplay. The battlefield is divided into four quadrants, and you can only aim within one quadrant at a time. This forces you to constantly rotate between quadrants and make strategic decisions on which area needs your attention the most.

The key to success in TETRAGUN lies in deliberate prioritization. As each wave ends, you have the opportunity to choose from a wide variety of upgrades that will enhance your survival chances and uncover powerful synergies. However, beware! Your enemies also gain access to upgrades and abilities that make them more formidable opponents.

One aspect that adds an extra layer of challenge is the scoring system. To truly master TETRAGUN, aiming for high scores becomes essential. Eliminating enemies earlier rewards higher scores, while quickly chaining eliminations boosts your score multiplier even further.

TETRAGUN offers diverse features that keep players engaged throughout their journey:

  • 25 unique turret upgrades give you countless possibilities for customization
  • 8 enemy upgrades add unpredictability to each encounter
  • A selection of 5 weapons allows experimentation with different playstyles
  • Powerful abilities offer tactical advantages when used strategically
  • Different difficulty levels cater to both casual players and seasoned veterans
  • Over 30 Steam Achievements provide additional challenges for completionists/li
