One of the most powerful and underrated units in Starcraft 2 is the Nydus Canal.

Available after you reach Lair tech, it can be built for 200 mineral and 200 gas.

This amazing building allows you to load it up with units and build a Nydus Worm at any target location you have visibility on.

Once the Nydus Worm pops out of the ground, you can begin spewing out the units you loaded in at your home bases Nydus Canal.

Sit back and watch as legions of roaches, hydralisks, zerglings, banelings, and more come spewing out ready to do damage.

The Nydus Canal also seems to hold a ridiculously large amount of units, compared to any other unit transport in the game.

Build multiple Nydus Worms and move your army around the map instantly.

Once you’ve learned how to master using the Nydus Canal you’ll see your Zerg game play evolve and become amazing.

With a few overlords you can establish sight on cliffs at the back of your opponents base.

Sneak up a Nydus Worm and take them by surprise.

When they come to meet your army, retreat back to the worm and let their army destroy your worm.

Sit back as your army is safe, as long as your Nydus Canal is safe.

Be careful, if your Nydus Canal gets destroyed with any units still in the canal, they will be killed along with all worms that exist on the map.

I hope this was informative. Have fun with the Nydus Network!
