Megabonk 100% Achievement Guide (Outdated)

Steam Community guide by Wibiz.

Introduction

This guide will go over how to get all 118 achievements in Megabonk. Most can be achieved through normal gameplay, but some require challenging runs or certain builds to complete. This is what this guide is for. Even though the game has descriptions on how to unlock everything, it's not always clear what's the best way to do it. I'm not pretending to know everything about the game, I just want to shed some clarity.
I'll only be focusing on 100% steam achievement completion, and I'll be categorising these by unlock method, not as the unlocks appear in-game. That does mean that character unlocks are intermixed with weapon unlocks, but I know you're not here to find the best way to "kill 15,000 goblins" or whatever. This is more intended for those harder achievements, while also encompassing everything else.
The guide is currently outdated as stated in the title, but I don't know when I'll update it, or if I need to. I'll do it if there's enough people asking for it, but as of now I don't really have plans to do it as I'm not focused on the game, and I can't really expect myself to keep up with Dani's new additions. But again, I'll still update it as long as I know someone wants it. Cheers.

Kill-based Achievements

These will be unlocked when you kill a certain amount of enemies with a certain weapon. Obviously these are easier to do with the character who has the weapon in question by default, the sword being a good example. Also note that "rockets" is referring to rockets from both the slutty rocket as well as the slutty cannon. i.e. kills from both count towards the same thing.

^(unlocking the weapon is harder than doing this; easier than it seems)

Easy achievements

These are the achievements that are easy to do if you're just aware of them. Like microwaving a certain item 3 times in a row, or picking an item because of what it can unlock. This list also includes those that are hard to avoid, like breaking pots or having a weapon work X amount of times.

^(This is a hidden achievement)

"Hidden" interactables

These are easy to spot, and the description makes it clear what you're looking for. However, here's further clarification on some of the details because some of them are not obvious:
1. For "Monke" you need to find two things: The cage and the key.
2. As long as you interact with each boombox you find, you're bound to get the achievement.
**3.**The "Santa Hat" is in a red box in the forest. It's hard to miss if you're looking for it.
**4.**The Old Mask is located on top of the tall towers in Graveyard. Every tower has one, so you can get multiple in a run, and the easiest way to access those spots is with Monke.
5. Bush and **Bandit **appear on all stages of their respective zones and they scale up accordingly, so just beat the ones in stage/tier 1.
6. The hidden items you can find can get collected despite your slots being full, resulting in 5 weapons for that run! In other words, you can keep playing as normal to find them.

Bananarang - Find the hidden Banana

Monke - Find and release Monke in the Forest

Boombox - Find and activate all the boomboxes on Forest

Santa Hat - Open the present hidden in the Forest

Old Mask - Find on Graveyard

Bush - Find and defeat Bush in the Forest

Bandit - Find and defeat Bandit in the Desert

Katana - 5% chance to find upon breaking a Tumbleweed on Desert Stage 1

Shotgun - 5% chance to find upon breaking a Tumbleweed on Desert Stage 2

Luck Tome - 0.01% chance to drop when killing an enemy

Weapon and Tome upgrade unlocks

These are all the achievements that you can get from upgrading weapons and tomes to a certain level. A general hint that might help here is that you can use the toggler, if unlocked, to restrict what you can find. However, the toggler only allows you to disable unlocks you've gained, not the stuff you've had since the beginning of the game. Having said that, these are all still easy to do without it. You just need to be aware of what tomes/weapons still need their upgrade unlocks

Battery - Upgrade Cooldown Tome to Level 5

Turbo Socks - Upgrade Agility Tome to Level 5

Turbo Skates - Upgrade both Cooldown and Agility Tome to level 5 in a run

Megachad - Get the Damage Tome to Level 7

Shattered Knowledge - Upgrade Attraction Tome to Level 8

Leeching Crystal - Upgrade Regen Tome to Level 8

Echo Shard - Upgrade XP Tome to Level 8

Athena - Get the Thorns Tome to level 9

Black Hole - Get Knockback Tome to Level 10

Sniper - Get Precision Tome to Level 10

Blood Magic - Get the Bloody Tome to Level 12

Dice - Get Luck Tome to Level 12

Duration Tome - Upgrade Axe to level 10

Wireless Dagger - Get the Lightning Staff to Level 15

Character specific achievements

Unlike the other achievements, these can only be gotten with a certain character. They're mostly just about killing enough enemies, or getting them to a certain level. The hardest part then, becomes unlocking these characters in the first place.

Desert - Teleport to the 2nd stage on Forest Tier 2 as CL4NK

Space Noodle - Complete Desert Tier 2 as Tony McZoom

Aegis - Block 500 damage with Armor as Sir Oofie

Dragon's Breath - Kill 1,000 Wisps as Fox on Desert

Gas Mask - Kill 5,000 enemies using amog

Armor Tome - Kill 5,000 enemies as Sir Oofie

Eagle Claw - Kill 10,000 enemies as Birdo

Rockets - Kill 15,000 enemies as CL4NK

Demonic Soul - Reach Level 30 as Calcium

Bloody Cleaver - Reach Level 50 as Vlad

Some boss-related achievements

Most of all of these achievements have some relation to beating the first stage boss, and they're easy enough to be grouped together. I'll add a little comment after each one though. Pretty explanatory achievements, but they need to be listed anyway.

Cursed Tome - Beat the Stage Boss in under 5 minutes
(You can do the "Speedrunner+" challenge on forest tier 1 to get this)

Speedboi - Complete a stage with at least 2 Boss Curse activated
(Boss curses stack, so for this you'll have three bosses to fight. Good luck)

Boss Buster - Defeat a Stage Boss in under 30 seconds
(30 seconds from within boss spawn to death. You'll get this without even knowing it)

Tactical Glasses - Defeat a Miniboss in 25s
(Not the stage boss, but you get the idea. Turn Chunkham into a chunk of ham)

Poison Flask - Kill Scorpionussy on Desert 3 times
(Self explanatory. For reference, Scorpionussy is the Chunkham of the Desert)
As you can surmise, most of these can be described with the age ol' saying "git gud", but that's true. These are achievements you're either getting very soon after starting the game, or later once you get stronger. The first two can double as challenge completions, and as long as you remember to use two boss curses on a good run, you're getting all of these no problem.

Challenge Count-based achievements

You need to complete 30 challenges within the game to get the final achievement in this category. There's some overlap with the other achievements, but you can't align all 30 with other unlocks. As an extension of this guide, I made a separate guide going over all the challenges I completed, and some tips for them. I felt like that was the best way to compress information. Check it out if you're interested, or just freestyle it. Either works fine. Anyway, you can find it here:

IMPORTANT: Since this has been made, the Graveyard map was added into the game, giving you more leeway for choosing your 30 challenges. So, the above guide is outdated, and will not be updated either, so take it with some pinch of salt. I
