Some achievements in John Carpenter's Toxic Commando unlock naturally as you play through missions and level your classes. Improper Use is not one of them. This one asks players to defeat enemies in a very specific way that most people probably would not even think to try during normal gameplay.

Instead of using your guns, abilities, or heavy weapons, the achievement focuses on environmental objects. Gas canisters can be picked up and thrown, and the game actually tracks kills that come from those direct hits. It sounds simple, but the key detail is how the enemies need to die.

How To Unlock Improper Use In Toxic Commando

To unlock the Improper Use achievement in Toxic Commando, you must kill 100 enemies by hitting them directly with gas canisters.

The important detail here is the direct hit itself. The enemy needs to die from the gas canister hitting them, not from an explosion that happens nearby after it lands. If the blast kills them instead, it will not count toward the achievement progress.

Because of that, you want to aim the throw and actually smack enemies with the canister rather than tossing it at the ground.

The Easiest Way To Farm Gas Canister Kills

The easiest place to work on this achievement is near the Pickup Truck. The back of the truck continuously generates gas canisters, which means you can keep grabbing them and throwing them without needing to search around the map.

Once you throw one, another eventually appears in the same location. This creates a steady supply of canisters that lets you repeat the process over and over while enemies keep spawning nearby.

Staying close to the truck turns this achievement from a slow grind into something you can steadily progress during a single mission.

Simple Method To Reach 100 Kills

The basic idea is to stay near the Pickup Truck and throw canisters into approaching zombies as they move toward your team. Basic enemies are the easiest targets because they go down quickly and tend to appear in large numbers.

Stay close to the Pickup Truck so canisters keep respawning
Wait until zombies start approaching your position
Aim the throw directly at the enemy instead of the ground
Repeat the process until the achievement reaches 100 kills

Once you get used to the throw timing, landing direct hits becomes much easier.

Tips That Make The Achievement Faster

Some small adjustments can speed things up quite a bit while working toward the 100 kills.

Focus on weaker enemies like Roamers
Let enemies move a little closer before throwing
Avoid using canisters on tougher enemies with high health
Throw directly at the zombie instead of near their feet

Basic enemies drop quickly from a solid hit, which helps progress the achievement much faster.

Final Blurb

Improper Use is one of those achievements that looks strange at first but becomes surprisingly fun once you start going for it. Instead of relying on your weapons, you end up turning gas canisters into improvised zombie projectiles.

The Pickup Truck makes this achievement much easier thanks to the constant supply of canisters in the back. Stay near the truck, keep throwing them into incoming enemies, and those 100 kills will add up sooner than you might expect.
