BUNNYBastion Speedrun Guide: Tips & Routes

Introduction to BUNNYBastion Speedrunning

BUNNYBastion, the fast-paced roguelite tower defense game from Last Wall Games, is perfect for speedrunning. With its 10-minute run structure, the game offers a tight, repeatable challenge where every second counts. This guide will break down the core strategies, optimal upgrade paths, and key techniques to help you shave time off your runs and climb the leaderboards.

Speedrunning in BUNNYBastion is about more than just fast reflexes. It requires a deep understanding of enemy wave compositions, the most efficient positioning for your defensive units, and the ability to make split-second decisions on upgrades. Whether you are a beginner looking for your first clear or a veteran aiming for a world record, this guide provides the foundational knowledge you need.

Core Speedrunning Strategies

Before diving into specific routes, you must master the core principles of speedrunning in BUNNYBastion. These strategies form the backbone of any fast run.

• Aggressive Positioning: Place your units as close to the enemy spawn points as possible. This reduces travel time for projectiles and allows you to clear waves before they spread out.
• Minimalist Builds: Avoid the temptation to build a complex network of units. Focus on a single, powerful unit type and upgrade it relentlessly. A streamlined build is faster to execute and easier to manage.
• Learn Wave Patterns: Each level has a set wave composition. Memorizing when tough enemies or bosses spawn allows you to prepare your abilities and upgrades in advance.
• Skip Unnecessary Upgrades: Not every upgrade is beneficial for speed. Avoid anything that increases your survivability if you are confident in your ability to dodge. Prioritize attack speed, damage, and area-of-effect.

Optimal Upgrade Paths for Fast Runs

Your choice of upgrades can make or break a speedrun. Here is a breakdown of the most effective upgrades to prioritize.

Early Game (Waves 1-5)

Your goal in the early game is to establish a strong foundation. Look for upgrades that provide immediate, high-impact damage.

• Attack Speed: This is your best friend. Faster attacks mean more damage per second and quicker wave clears.
• Single-Target Damage: Prioritize this for dealing with the first few elites.
• Area of Effect (AoE): While powerful later, early AoE can be less effective due to low enemy density. Only take it if it is a significant upgrade.

Mid Game (Waves 6-10)

As enemy density increases, AoE becomes crucial. You should also start looking for synergy upgrades.

• AoE Radius and Damage: These are now your top priority. You need to clear large groups of enemies in seconds.
• Projectile Count: Abilities that fire multiple projectiles are excellent for covering the map.
• Critical Hit Chance and Damage: A strong critical hit build can melt bosses and elite packs.

Late Game (Waves 11-15)

The final waves are a test of your build's power. You should be looking for upgrades that multiply your existing strengths.

• Damage Multipliers: Any upgrade that says "deal X% more damage" is a must-take.
• Ultimate Ability Cooldown Reduction: Your ultimate is a run-saver. Use it as often as possible.
• Piercing: This allows your attacks to hit multiple enemies in a line, which is incredibly efficient for the final waves.

Recommended Speedrun Route

While BUNNYBastion features procedural elements, you can follow a general route to maximize your speed.

1. Start with a High-Damage Unit

   Begin your run by selecting a unit that offers high single-target damage. This will help you clear the first few waves quickly and build an early lead.

2. Prioritize Attack Speed Upgrades

   For your first two upgrade choices, focus exclusively on attack speed. This will dramatically increase your clear speed for the first half of the run.

3. Transition to AoE by Wave 6

   By wave 6, you should have your first AoE upgrade. If you haven't found one, consider restarting. This is the most critical phase for a speedrun.

4. Maximize Your Ultimate Usage

   Do not hoard your ultimate ability. Use it as soon as it is available, especially on waves with high enemy density or tough elites.

5. Focus on the Boss's Weak Points

   During the final boss fight, learn its attack patterns and focus your damage on its weak points. This is where your single-target damage from the early game will pay off.

Common Mistakes to Avoid

Even experienced runners can fall into these traps. Avoid them to keep your runs on track.

Advanced Techniques

Once you have mastered the basics, try incorporating these advanced techniques to further improve your times.

• Unit Stacking: Place multiple units of the same type on the same tile to concentrate their firepower. This is a risky but highly rewarding strategy.
• Wave Skipping: In some cases, you can kill enemies so fast that the next wave spawns immediately. Learn which wave combinations allow for this to save precious seconds.
• Perfect Upgrade Rerolls: Know when to reroll for a better upgrade. If the offered upgrades are all bad, it is often faster to take a mediocre one than to waste time rerolling multiple times.
