Steroids is the only character that has the ability to shoot both of their weapons at the same time. Steroids shoots inaccurately but starts with more ammo than other characters and all weapons used by them are fully automatic.
- Steroids starts with a Revolver in both primary and secondary weapon slots and 160 bullets instead of 96. If Steroids starts with a Golden Weapon in their primary weapon slot, they will have some ammo for it and 64 bullets for the Revolver in their secondary weapon slot. They can't start with two Golden Weapons.
- Steroids has less accuracy. With weapons that shoot multiple projectiles in a spread, the spread will be wider. Steroids' base inaccuracy rating is 1.8 (up from 1 for all other characters), resulting in 80% more inaccuracy when firing.
- It's also worth noting that because this effect is a multiplier and not a flat increase, guns with perfect accuracy are not affected. These weapons include the crossbow, heavy crossbow, laser cannon, golden laser pistol, golden grenade launcher, and most melee weapons (that is, excluding shovels and screwdrivers).
- In addition all weapons used by Steroids are fully automatic, including melee weapons. Holding down the fire button will fire/swing the weapons constantly as they reload automatically.
- Steroids dual wields their weapons, allowing them to shoot and reload two weapons at the same time. The button used to activate special abilities is used to fire their secondary weapon.
- Firing with your primary weapon may add a small amount of ammo for your secondary weapon and vice versa. The chance and amount of ammo you receive depend on what type of weapons you have. Mainly how much ammo they use per shot and how much ammo they receive from Mini Ammo Chests. This is more likely to occur when both weapons are being fired at once. This mutation doesn't work if you have at least one melee weapon that doesn't use ammo.
- The amount of ammo you can receive per shot is equal to a half of a Mini Ammo Chest pickup. Bullet weapons would get +16 ammo, shell weapons would get +4 ammo etc. The amount gets rounded up for bolt weapons.
- The chance per shot to receive ammo for the other weapon (the one you are not firing at the moment) equals:
- (Ammo used per shot/Mini Ammo Chest size for the weapon you are firing)*1/2
- Let's say you have a Machinegun (ammo used = 1, ammo drop size = 32) and your other weapon is a Double Shotgun (ammo used = 2, ammo drop size = 8) then:
- If you fire the Machinegun it would be: 1/32*1/2 = 1/64 = 1.56% chance to get 4 shells per Machinegun shot.
- If you fire the Double Shotgun it would be: 2/8*1/2 = 1/8 = 12.5% chance to get 16 bullets per Double Shotgun shot.
- If you are firing both weapons at the same time, the multiplier changes from 1/2 to 2/3 and the chance to get ammo rises:
- (Ammo used per shot/Mini Ammo Chest size for the weapon you are firing)*2/3
- Following the example, it would be:
- If you fire the Machinegun it would be: 1/32*2/3 = 1/48 = 2.08% chance to get 4 shells per Machinegun shot.
- If you fire the Double Shotgun it would be: 2/8*2/3 = 1/6 = 16.67% chance to get 16 bullets per Double Shotgun shot.
AmbidextrousWeapon Chests and Cursed Weapon Chests increase in size and drop two of the same weapons.
Large Weapon Chests drop four random weapons instead of three.
Get LoadedAmmo Chests increase in size and have 10 Mini Ammo Chests inside, giving two for each type (bullet, shell, bolt, explosive and energy). Present Ammo Chest also contain as much ammo as regular Ammo Chest.
- Steroids excels at taking on large groups of enemies at once and relying on sheer firepower to finish engagements before enemies can react. Their Throne Butt is a crucial upgrade, as it gives you the ammo conservation to make this a viable tactic. A great tactic, especially for the Sewers levels, is to take a melee weapon in the off hand, allowing you to quickly reflect projectiles and deal with melee enemies, giving Steroids a great amount of survivability, as well as off setting their increased ammo consumption due to the accuracy loss. Steroids' lower accuracy affects all spread-related weapons, from Super Crossbows and Shovels to Triple Machineguns and Laser Miniguns.
- Useful mutations:
- Throne Butt - reduces overall ammo consumption by regenerating ammo for your other weapon
- Rabbit Paw - even more ammo drops.
- Back Muscle - provides higher max ammo which lets you auto fire for longer.
- Eagle Eyes - nullifies Steroids' passive accuracy loss.
- Recycle Gland - when paired with Steroids' Throne Butt, allows them to fire bullet weapons without regard for ammo.
- Bolt Marrow - Mitigates the low accuracy when using a bolt weapon.
- Euphoria - to make reflecting projectiles easier if you have a secondary melee weapon.
- Open Mind - since Steroids is mostly based around dual-wielding and both their Ultra Mutations involve chests, an additional weapon chest or ammo chest gives the player more variety of weapons and extra ammo for them.
- Long Arms - good for a melee and ranged weapon combo. Increases the range at which you can reflect projectiles and deal melee damage while firing your other weapon. Note that Throne Butt and Long Arms should not be picked in the same run if you have a melee weapon that doesn't use ammo.
