BUNNYBastion Guide — A Complete Beginner Walkthrough

Welcome to this BUNNYBastion guide — your complete resource for mastering this fast-paced roguelite defense game. Whether you are a newcomer or a returning player, this BUNNYBastion guide covers everything you need to know about defending your fortress against waves of enemies, choosing the right upgrades, and building permanent progression across runs. Developed by Last Wall Games and released on June 9, 2026, BUNNYBastion combines automatic attacks with precise aiming and active skill usage, creating a unique blend of action and strategy that rewards both reflexes and planning.

Getting Started in BUNNYBastion

BUNNYBastion runs are designed to be quick, lasting approximately 10 minutes each. When you start a run, enemies approach your bastion from a single direction. Your attacks fire automatically, but you must aim precisely and use your skills at the right moments to survive. After each wave of enemies, you are presented with a selection of roguelike upgrades. These upgrades shape your build for the current run and can dramatically change your playstyle. Choose wisely the right combination of upgrades can turn a difficult encounter into a breeze, while poor choices can leave you overwhelmed.

Permanent progression is a key part of BUNNYBastion. Even when you fail a run, you earn currency that can be spent on unlocks and upgrades that carry over to future runs. This means every attempt makes you stronger, and no run is ever wasted. Focus on learning enemy attack patterns and wave compositions first, then optimize your upgrade choices as you unlock more options.

Core Defense Strategies

Successful defense in BUNNYBastion requires balancing three elements: positioning, aim precision, and skill timing. Since attacks are automatic, you can focus entirely on where to point your weapon and when to activate your skills. Here are the core strategies every player should master:

Understanding the Upgrade System

The upgrade system is the heart of BUNNYBastion replayability. After clearing each wave, you choose from several random upgrade options. These fall into several categories: weapon upgrades that increase damage or add new attack properties, skill upgrades that reduce cooldowns or enhance effects, defensive upgrades that improve your survivability, and utility upgrades that provide special bonuses. Building a synergistic set of upgrades is the key to clearing later waves. For example, pairing an upgrade that increases attack speed with one that adds splash damage can clear grouped enemies efficiently.

Permanent Progression and Unlocks

Between runs, you can spend currency earned during your attempts to unlock permanent upgrades. These persist across all future runs and include stat boosts like increased starting health, better weapon damage, and additional skill slots. Prioritize unlocks that complement your preferred playstyle. If you favor aggressive play, invest in damage-oriented permanent upgrades first. If you prefer a slow and steady approach, defensive unlocks will serve you better. The permanent progression system ensures that every run contributes to your overall power growth, making even failed attempts valuable learning experiences.
