	The Mine Layer Tripmine Launcher Alt-Fire: Fizzle all tripmines Tripmines explode when laser is crossed Tripmines are able to chain-react Tripmines have increased radius and damage 4 max tripmines active ; "Aye, keep an eye out! Heh..."

The Mine Layer is an alternative secondary weapon for the Demoman. It appears similar to the Stickybomb Launcher, but features a cylindrical magazine, a circular ejection port, and a large metal chassis with yellow warning paint on its side. The paint appears yellow regardless of which team the user is on.

As opposed to the Stickybomb Launcher's manually detonated stickybombs, the Mine Layer fires tripmines that detonate when enemies or the user cross their laser (unless they are a disguised or cloaked Spy). They also detonate any nearby tripmines placed by the user in the process. Compared to stickybombs, tripmines deal 35% more damage and have a 35% larger blast radius.

Tripmines take 2 seconds to arm upon attaching to a surface, and 0.15 seconds to detonate after being triggered by an enemy. When triggered by the user, tripmines will instead detonate after 0.5 seconds to make blast jumping easier. After arming, tripmines emit a glowing laser that fades out over long distances. They also have a flashing light and make a quiet beeping sound, warning enemies of their presence. When triggered, they make a loud beeping sound.

The Mine Layer's alternate fire fizzles out tripmines without an explosion, regardless of if they're armed or not. If the user attempts to deploy another tripmine when four are already out, the oldest one placed will fizzle. Mines also persist after the user's death.

Reduced player detection radius of proximity mines by 20% of their explosion radius
Reduced detonation delay of proximity mines to 0.4s vs enemy players (from 0.5s)

Note: We are still experimenting with this item, but these changes were positive in most iterations. They made mines more predictable and gave players more tools to remove them, which made falling for a trap feel much more fair.

Trivia

The Mine Layer's model was originally submitted to Team Fortress 2's Steam Workshop in 2011.
Its magazine can visually house up to 6 mines but only holds 4 in-game for balancing purposes.
The Sandvich is able to detonate enemy mines.
The beeping of deployed mines have a different pitch for each team, following the easily replicable formula Pitch = 86 + GetTeamNumber() * 4, where RED = 2, BLU = 3, GRN = 4, and YLW = 5. They have the lowest pitch on RED and the highest on YLW.
