A gas powered industrial strength chainsaw. This tool may rely on a steady supply of gasoline, but it can cut through a variety of surfaces with ease. —Trader description 

The chainsaw is as powerful motorised melee weapon for Berserkers. It has two firing modes usable with the primary and secondary fire buttons. Primary has a high rate of attack but low damage, secondary is the opposite; a powerful swing of the chainsaw which can stun specimens and does large amounts of damage whilst still possessing a relatively high rate of attack. It is the only melee weapon to not give a speed boost and by default is never found in random weapon spawns. It is the only weapon with a damage reduction on a headshot.


The Berserker perk gets bonuses and a discounts for the chainsaw, and spawns with one from level 5. For head shot damage, divide by 4.

The base cost of the chainsaw is £1000, this can be reduced by up to £701 with use of the berserker perk, at intervals of £100 per level. As with all melee weapons there are no maintenance costs for it, it also doesn't require fuelling up to function as the trader description made out.


Unlike all other weapons the chainsaw should never be used to decapitate powerful targets; it has a 0.25 multiplier on a headshot which means that against specimens that have head health higher than a quarter of its total health its quicker to rip through their chests or another body part instead. This applies to the Crawler, the Husk, the Siren, the Scrake, the Fleshpound and the Patriarch. The Gorefast, the Bloat and to a much lesser extent the Clot are the only specimens that headshots are worthwhile against. Stalkers have exactly a quarter head health, and therefore can be killed with the chainsaw at the same speed with or without aiming for the head.


As with all Berserker equipment, it is ill advised to encounter Fleshpounds or the Patriarch with it on higher difficulties. Sirens, and to a lesser extent Husks and Bloats, can also be a problem due to their ranged attacks; ambush tactics and hit and run manoeuvres can be useful against them. Scrakes and smaller all suffer a stun effect from the chainsaw's alternate fire, making them easier to kill and will likely also earn you the Bitter Irony achievement. Due to their size and speed, Crawlers are likely to cause a berserker grief, holding primary fire and aiming at the angle they jump is one solution, another option is to simply swap to a gun and deal with them before they get in range.
