Two controllers are highly recommended for this game as the mouse controls are terrible and keyboard controls are non-existent.

Two controllers are all that's needed for every achievement, though Destroyer and Maniac need 4 players. The mouse can be player 3 and a bot can fill in the last slot or you can play online with a friend.

I assume every achievement can be boosted with a friend online, but this guide was written in mind with everything done locally.

Freshman
Get 10 kills

See Gladiator.



Seasoned Fighter
Get 50 kills

See Gladiator.



Gladiator
Get 100 kills

Self-explanatory. You need to kill your opponent(s) to end the round. I'm unsure if kills by your guest accounts count towards this total.

Sniper
Unlock Luna

Everything in the game is unlocked by simply finishing matches. Lower the "Match Points" parameter under Match Settings to finish matches faster. Luna is unlocked after finishing 2 games.



A little bit of magic
Unlock Wizardo

Wizardo is unlocked after finishing 7 games.



Rabbit's foot
Unlock Bongo

Bongo is unlocked after finishing 25 games.



Style Wizard
Unlock all Wizardo skins

There is something bugged with this achievement. You're supposed to play matches as Wizardo to unlock all his skins, but it unlocked for me randomly upon starting the game.

Spoiled pancake
Win a match for the first time

Easy. Still counts even with local players only.



Space Gladiator
Win 50 matches

You'll get this one eventually. Remember you can lower "Match Points" under Match Settings for shorter matches. While there's no way to check how many matches you've won, the final arena: Floor is Lava unlocks after playing 43 matches, so a rough guess can be made from there.



Burn!
Win during Sudden Death

You must win the match during Sudden Death, and not just win a round. Sudden Death starts after the Round Time depletes and the arena starts filling up with flames.



But WHYYY?!
Kill yourself while being the Survive To Win challenger

The Survive To Win round is the final round after you score enough Match Points. You can kill yourself by standing near a powerup and shooting it, or any one of the many environmental hazards in the later maps.

Delicious
Eat 10 nachos

See Nacho Monster.



Nacho Monster
Eat 1000 nachos

Nachos spawn at the start of every round. Collecting 1 nachos gives you one point.
Select the Walls Are Moving! arena (four nachos and easy kill to finish the round) and play as Luna (she runs fastest). You must collect 1000 total across all matches for the achievement - making this the longest grind in the game.



Nacho Victory
Eat all nachos on any map during one round

Probably the easiest achievement in the game. Simply pick up every nachos that spawns at the start of any round.

Bouncy
Kill any character after your bullet bounces 3 times

See Bounciest. The bullet must bounce 3 times, not more.



Bouncier
Kill any character after your bullet bounces 5 times

See Bounciest. The bullet must bounce 5 times, not more.



Bounciest
Kill any character after your bullet bounces 7 times

Easily done with a two controllers. Start a match on the Bouncy Corridors arena (with any character that has standard bullets) and bounce your shot between the two walls in the middle. Count the number of bounces needed and stand the second player at the appropriate location.

U mad?
Kill someone by deflecting a bullet

Umad's ability allows him to reflect bullets. Have you partner shoot you and deflect the bullet back at them.



But how?!
Kill someone by shooting through a warp

At the edges of most arenas are warps that allow you to wrap around to the side. Simply shoot through the warp and kill someone on the other side.



Handyman Extraordinaire
Get 10 kills using environment only

I believe Environment Kills are any kills that aren't inflicted directly by your bullets. An easy arena to do this on is Transmitter Belt. Simply stand the victim(s) on the conveyor belt and press the large red button. Alternatively, lots of the later maps also have easy Environment Kills.



Bad touch
Get 10 kills using Deathtouch

Deathtouch is a powerup that first appears on the Overgrowth arena. Grab it and run into your opponent for an easy kill. Repeat 10 times.



Revenge of the dead
Get 10 Necro kills

See Let there be darkness on how to perform consistent Necro kills. Repeat 10 times.



Let there be light
Kill someone by teleporting on them

Wizardo's ability allows him to teleport. Use it once to throw a teleport destination, stand your partner on the portal, then use your ability again to telefrag your partner.



Let there be darkness
Kill someone by teleporting your dead body on them

Same as Let there be light except have your partner shoot you before teleporting. This can still be done with two players as there's a slight delay after the kill and the round ending - giving you enough time for the telefrag.



Destroyer
Kill 3 other players in one round

Can be easily done with 3 controllers and mouse as 4th, or against bots. Bots might take a few tries as they may steal your kills.



Maniac
Kill 3 other players and yourself in one round

Can be done with 3 controllers and mouse as 4th, or against bots. Kill the bots first (if any), then stand your partner and yourself near a powerup and shoot it so it kills both of you.



Denied
Cancel 1000 bullets

Two controllers is strongly recommended for this achievement. Disable Sudden Death and select two players who shoot single bullets (e.g. Dr. Peakl & Wizardo). Line both players up so that your bullets hit each other and repeat.

Pacifist
Win any round without using your weapon or ability

Easily done during sudden death or having your opponents suicide.



Flames of love
Win a match as Chuck without shooting

Self-explanatory. Use his charge ability to kill.



Slow and steady
Win a match as Mia without dashing

Self-explanatory.



Spike Hell
Win a match as Dr. Peakl without shooting

Self-explanatory. Use his spikes ability to kill.



Umadness
Win a match as Umad without shielding

Self-explanatory.



In plain sight
Win a match as Luna without entering stealth

Self-explanatory.



Zoomies
Win a match as Wizardo without shooting

Self-explanatory. His teleport can telefrag or just play on any arena with the Deathtouch powerup.



Octoboom
Win a match as Bongo without shooting

Self-explanatory. He can kill with mines or just use the Deathtouch powerup.

While unrelated to achievements, the following is all the stuff that can be unlocked in game. Everything is unlocked for playing matches.




Skins are unlocked by playing games with that character. Each character has 5 skins: 2 available from the start, and the rest unlock after 5, 10, and 20 games.
