BUNNYBastion Achievements Guide: Full List & How to Unlock

Introduction to BUNNYBastion Achievements

BUNNYBastion, the fast-paced Roguelite tower defense game from Last Wall Games, launched on June 9, 2026, with a robust set of achievements for PC players on Steam. This guide covers every achievement in the game, how to unlock them, and strategies to earn them efficiently. Whether you are aiming for 100% completion or just looking for specific trophies, this is your go-to resource.

The achievement system in BUNNYBastion is designed to track your mastery across multiple runs. With each 10-minute session, you can make progress toward several goals simultaneously. There are no missable achievements tied to a single playthrough, so you can always return to unlock what you missed.

Achievement Categories and Tiers

BUNNYBastion divides its achievements into several categories based on difficulty and gameplay focus. Understanding these categories will help you plan your unlocking strategy.

The main categories include:

• Progression Achievements: Unlocked by reaching specific milestones in the game's progression system, such as completing your first run or reaching a new difficulty tier.
• Combat Achievements: Earned by defeating certain numbers or types of enemies, including elite enemies and bosses.
• Upgrade Achievements: Tied to purchasing and maxing out various upgrades from the in-run shop and permanent meta-progression.
• Secret Achievements: Hidden achievements that require specific actions or combinations during a run. These often have unique unlock conditions.

For a full breakdown of the progression system, see our Progression Guide.

How to Unlock All Progression Achievements

Progression achievements are the backbone of your journey in BUNNYBastion. They reward you for simply playing the game and advancing through its systems.

Here is the list of progression achievements and how to unlock them:

Combat and Enemy Elimination Achievements

Combat achievements are all about defeating enemies in specific ways or in large numbers. These are often easier to grind once you have a strong build.

Key combat achievements include:

• Bunny Slayer: Defeat 1,000 enemies total. This will come naturally as you play.
• Elite Hunter: Defeat 50 elite enemies. Elite enemies are tougher variants that spawn from wave 5 onward. Learn their patterns in our Elite Enemies guide.
• Boss Buster: Defeat each of the 5 boss types at least once. Bosses appear every 5 waves.
• Perfect Defense: Complete a run without losing any health. This requires a defensive build with healing and shields.
• Glass Cannon: Defeat a boss within 10 seconds of it spawning. Stack damage upgrades and use burst abilities.

Upgrade and Economy Achievements

These achievements focus on the economic and upgrade systems of BUNNYBastion. They reward smart resource management.

Secret Achievements and Hidden Challenges

BUNNYBastion features several secret achievements that are not listed in the game's achievement menu until unlocked. These often require specific, sometimes quirky, actions.

Here are the known secret achievements:

• Bunny Hop: Jump 100 times in a single run. This is purely for fun and easy to unlock.
• No Touch: Complete a run without your character taking any damage. This is a harder version of "Perfect Defense."
• Speed Demon: Complete a run in under 8 minutes. This requires aggressive play and prioritizing speed over defense.
• All In: Win a run with only one tower placed. This is a self-imposed challenge that tests your tower's effectiveness.
• The Floor is Lava: Do not place any towers on the ground for the first 10 waves. Use elevated or wall-mounted spots instead.

Tips for Efficient Achievement Hunting

To maximize your efficiency while hunting achievements, follow these strategies:

1. Plan Your Runs: Before starting a run, decide which achievement you are targeting. Build your loadout and strategy around that goal.
2. Use the Right Character: Each character has unique abilities that can make certain achievements easier. For example, the "Engineer" character is great for "Maxed Out" due to reduced upgrade costs.
3. Stack Achievements: Try to combine multiple achievements in one run. For instance, you can work on "Deep Pockets" and "Shopaholic" simultaneously.
4. Learn Enemy Patterns: Knowing when and where enemies spawn helps you plan tower placements for achievements like "Perfect Defense." Check our Gameplay Overview for more details.
5. Don't Ignore the Meta-Progression: Permanent upgrades make every subsequent run easier. Focus on unlocking these first to reduce the difficulty of harder achievements.
