BUNNYBastion Review: A Fast-Paced Roguelite Tower Defense

Overview: What is BUNNYBastion?

BUNNYBastion is a fast-paced Roguelite tower defense game developed and published by Last Wall Games. Released on June 9, 2026, exclusively for PC via Steam, it blends action, strategy, and casual elements into compact 10-minute sessions. The core premise is simple: defend your bastion against waves of enemies, select powerful upgrades after each wave, and see how far you can push your build. The game’s vibrant art style and quick loop make it easy to pick up but challenging to master, offering a refreshing take on the tower defense genre.

Gameplay and Core Mechanics

The gameplay loop in BUNNYBastion is tight and rewarding. Each run lasts roughly 10 minutes, making it ideal for short play sessions. You start with a basic defensive setup and earn resources by defeating enemies. Between waves, you are presented with a choice of upgrades—these can range from new tower types, stat boosts, or special abilities. The Roguelite element means that when you fail, you restart from the beginning, but you retain some permanent progression. This encourages experimentation with different strategies and upgrade paths.

Visuals and Sound Design

BUNNYBastion features a charming, colorful aesthetic that is both whimsical and clear. The character and enemy designs are distinct, making it easy to read the battlefield at a glance. The UI is clean and intuitive, ensuring you can make quick decisions under pressure. The sound design complements the action with satisfying attack sounds and a dynamic soundtrack that ramps up during intense waves. The overall presentation feels polished and contributes to the game’s addictive “one more run” quality, as noted in our Gameplay Overview.

Upgrades and Progression System

The upgrade system is the heart of BUNNYBastion’s replayability. You will encounter a wide variety of upgrades that can synergize in unexpected ways. For example, combining a fire tower with a damage-over-time upgrade can melt through enemy hordes. The permanent progression system, detailed in our Progression Guide, allows you to unlock new starting loadouts and passive bonuses. This ensures that even failed runs contribute to your overall strength, a hallmark of the Roguelite genre. For a comprehensive list of all upgrades, see our Upgrades Guide.

Replayability and Content

With its Roguelite structure, BUNNYBastion offers high replay value. The random nature of upgrade choices ensures that no two runs are exactly alike. Additionally, the game features multiple difficulty levels and challenge modes that test your skills. For players looking to optimize their runs, our Character Builds Guide provides advanced strategies. The game also includes a collection system for characters and units, adding another layer of depth for completionists. Learn more about collecting characters in our Character Collection Guide.
