Which Demo Weapons count for the Left 4 Heads Achievement

Question

The Left 4 Heads achievement is to behead 4 people in 10 seconds. Which of the demo melee weapons count as beheading as per the achievement?

I know that obviously the Eyelander will, since it debuted with the achievement in the first place, but what about the new swords since? The axes?

Answer 1

All weapons that can decapitate will work with the achievement, including those which do not buff you based on how many heads you've taken in a life. That means all these:

• Eyelander
• Scotsman's Skullcutter
• Horseless Headless Horsemann's Headtaker
• Claidheamh Mòr
• Half-Zatoichi

It does make things easier if you equip weapons that help you run faster, like the Eyelander or the HHHH. I wouldn't use the Skullcutter for it.

Obviously, you have to be a Demoman to get the achievement using the Half-Zatoichi; it won't count if you're a Soldier.

Answer 2

From the Obtaining Demoman Achievements page on the official TF2 wiki:

Left 4 Heads

Decapitate 4 players with only 10 seconds between each kill.

Difficulty: Hard
How to obtain: Equip the Eyelander, Scotsman's Skullcutter, Horseless Headless Horsemann's Headtaker, Claidheamh Mòr, or Half-Zatoichi and engage multiple enemies at close range. Pair your melee weapon with the Chargin’ Targe in order to reach new targets before the ten seconds expire.
