Tips

 * Semi-automatic firing can be countered by simply adding an alternative way of firing on 'scroll up' or 'scroll down' through the key binding customization.

Trivia

 * Before Update 10, Saryn + Mire + Torid + Acrid would give you the only loadout consisting solely of toxin.
 * Alternatively, one can use the Dual Ichors in place of the Mire for more damage. They also deal pure Toxin damage vs. the Physical damage of the Mire.
 * The Acrid is physically the largest handgun in Warframe.

Bugs

 * Acrid will not change its proc damage type in game regardless of mods. (eg, changing it to viral will still show toxin procs in game). This causes less DoT damage to robotics.
 * Currently procs every single shot, or a very high percentage.
