Monkey Engineer (BTDS)

The Monkey Engineer, or sometimes just Engineer is a tower that first appeared in BTD5 and reappears in Bloons Tower Defense Siege. As of July 30th, it is absent from BTD6. The tower fires nails from its nail gun that pop bloons. Its upgrades allow it to make sentry turrets, boost other towers, or clear bloon properties. It is classified as a Military tower. Compared to it's BTD5 counterpart, this Engineer costs slightly more to purchase but has better range and slightly better attack speed.

Mechanics
The monkey engineer, at base, is a really simple tower. They shoots nails over Boomerang Monkey range that pop 1 layer off of up to 2 bloons and they attack 1.7 times every second. Their attacks cannot pop lead or frozen bloons.

Path One
Tier One: Sentries

The monkey engineer can make sentries within its range. These sentries are long ranged and fire nails that pop 1 layer off of up to 2 bloons. They attack at a rate of 1.5 attacks per second. A maximum of 3 sentries can be built, and when one disappears, there is a delay between making another one. Normally, sentries are made every 10 seconds, but it can be sped up b attack speed boosts.

Desc: Periodically creates sentries to shoot at bloons.

Appearance: The monkey's helmet is now a lime green.

Cost: $550

Tier Two: Fast Engineering

The engineer makes sentry guns every 6 seconds instead of 10 and can make up to 5 sentries.

Desc: Allows the engineer to make more sentries at a faster rate.

Appearance: The monkey's helmet is now a cobalt blue.

Cost: $400

Tier Three: Sprockets

Both the engineer and the turrets get a 25% attack speed boost.

Desc: Increases sentry and nail gun fire rate appreciably.

Appearance: The monkey's helmet is now black. The nail gun and sentries have several small gears protruding out of them that slowly spin. On the waist of the tower, there is now a brown leather belt with
