I love that little gun! Click to listen — The Engineer on his Combat Mini-Sentry Gun

”

The Combat Mini-Sentry Gun is a more combat-efficient version of the standard Sentry Gun and is a component of the Engineer's Gunslinger unlock. It is a smaller Level 1 Sentry Gun outfitted with a rotating light that glows and is painted with a white checkered paint. Like the Sentry Gun, it can be hauled.

Advantages

• Costs only 100 Metal to place (the normal Sentry costs 130 Metal). This allows an Engineer at a full 200 Metal to build both it and a Dispenser without needing additional Metal.
• Constructs much faster than the original Sentry Gun. Hitting the Sentry makes it construct faster and, when deployed after hauling, it is armed in 1.5 seconds.
• Cheap and disposable means of area denial.
• Begins construction with 50 health. This makes the Mini-Sentry less vulnerable while under construction when compared to the default Sentry Gun, which begins construction with 1 health.
• Fires 25% faster than a Level 1 Sentry Gun.
• Can rotate 35% faster than the default Sentry Gun.
• 75% the size of a regular Sentry Gun, making it harder to notice and hit.
• More useful for Sentry jumping, as the firing rate and reduced damage combine to deal more knockback for an equivalent health loss.

Disadvantages

• Has only 100 health, compared to a Level 1 Sentry Gun's 150.
• Cannot be upgraded. The owner and other Engineers can still refill its ammo and health.
• Deals only 50% the damage per shot of the original Level 1 Sentry Gun. Combined with the 25% faster firing rate, the damage per second is overall 38% lower (~50 DPS compared to the Level 1 Sentry Gun's ~80 DPS).
• Bullets apply significantly less knockback force (800% knockback multiplier compared to a regular Sentry Gun's 1600% multiplier).
• Drops zero Metal when destroyed.
• Once a Sentry jump is executed, not exceptionally useful as part of a base in the new area.

Disposable Mini-Sentry

In Mann vs. Machine, the Engineer can buy a Disposable Sentry that at first glance just looks like a normal Combat Mini-Sentry Gun, however there are a few differences:

• Has a slower firing speed than a normal Mini-Sentry.
• Cannot be repaired or have its ammo refilled.
• Cannot be destroyed by the Engineer who made it - it can only be destroyed by an enemy robot or automatically destroyed when the wave ends or the Sentry runs out of ammo.
• Cannot be wrangled, but still receives canteen buffs.
• Is 66% the size of a normal sentry compared to the Combat Mini-Sentry's 75%.
• Is not affected by the building health upgrade (always has 100 max health).
  • However, it is affected by the Sentry Firing Speed upgrade.
