Hey there TL.net. I’m going to introduce you all to a new little tactic you can use as the swarm to defeat the almighty lasershooting beast of the protoss.

Introduction of the glitch:
The glitch I discovered was that the colossi has got a unique pathing calculation which causes it to interact with burrowed movement in an interesting way. In the youtube video below you can clearly see that burrowed roaches and infestors prevent the movement of any colossi but not the rest of the protoss army. This also only works with the roaches and infestors due to their mechanic of burrowed movement even if tunneling claws is not even researched.


Possibilities of using this glitch:
Just by theorycrafting so far there’s quite a lot of uses for this glitch and it makes the roach more viable for the mid to late game in PvZ. The trick itself relies on the lack of observers together with the protoss main army, this could prove to be a problem but there are techniques to circumvent this. The most apparent one is the various observersnipes which are perfect ways to slow down the P gas progression, but my favorite one use the overseer’s amazing ability contaminate. Contaminating the robotics bay creates pressure on the P to reach his critical mass colossi and thus he might skip out on observer production. So a combination of these and maybe other tricks might render the protoss army without observers.
[image loading]
This glitch also accomplishes to split up the protoss army so you can either engage the protoss army without colossi support or flank the colossi with roach/corruptor when he lacks stalker support and this is only the most apparent possibilities, a split up protoss army just begs to be abused in all possible ways.

Synergies with strategies:
The roaches themselves are quite commonly used to combat the normal colossi supported protoss armies. The corruptors are crucial for fighting of the colossi in a normal ZvP and the overseer is an amazing unit to have both offensive and defensive, this will allow you to have a competent observersniping force even without messing with your standard armycomposition. The only investment you need to do is the burrow tech which you get for the mere 100/100 resources and you even need that if you’re going for tunneling claws for roaches anyway. The lurkers themselves that you endanger with placing in chokepoints are often not worth more than the sc:bw hold-lurkers and the reward for successfully splitting the protoss main army can be huge exploited in the right way.

Epilogue:
This is just the tip of the iceberg of a new glitch and I’d love to hear your thoughts and ideas regarding how you can use this mechanic, be creative, discuss and try out.

Recognized replays:
Will keep an eye out once this trick gets used by the pros!


Until next time, Steve Urkl lurks on! =))
If the facts dont fit the theory, change the facts.

Glitch, not a trick. It will be patched.

Strange to see this happen however. I have played games where they have walked right over. Possibly from recent patching, which wouldn't explain why they needed to patch this mechanic.

Very nice find. Excellent, well researched post.
It's not as broadly applicable a bug as fazing but I do see how it has potential.

This is also basicaly useless, any good toss will have obs and just kill your roaches

better for protoss cuz now if u pay attention you know if there are burrowed roaches. For example i could have him patrol across my ramp and if i see him fuck up i know roaches are coming into my base

Lol, what an obvious bug. You seriously think this counts as a trick? Don't even waste your time trying to abuse this as it won't stay in the game for long.

Agree with this.

As much as you might want this to be the next muta-stacking or moving shot, this is a bug that will be fixed.

I dont see how would be effective at all. Not like your going to burrow a bunch of roac to mess up AI because they will have an obs.

colossus are large so i imagine burrowing a couple spread apart could fuck them up, especially if they dont expect it

This needs to be fixed though

Good lord people, give the guy some credit -_-

The overlord+muta control group in BW was technically a bug, just like hold position lurkers. The only reason they still exist is because BW isn't worth patching anymore. Good find, Urkl.

They exist cause they are bugs in the engine itself, BW was still being patched when these were discovered(muta stacking) and hold lurkers had been out forever

Seriously an interesting find-- especially considering after such an extensive beta/alpha testing phase-- how was this missed? I wonder if it will be patched.

Sidenote: If the burrowed units surround the collo's, does it become trapped?
10% of the time, I am awesome.

I'm assuming it would take a lot of roaches and infestors to block a collosi

seems a little to risky to risk all those units just hoping that the Protoss doesn't have observer

and yes. If it's a "glitch" then it will be fixed

interesting find tho

I think it might of arisen after the last patch.

I've seen Collosus go over burrowed roaches fine before.

That's pretty messed up, haha... Seems like a pretty glaring glitch to be in there. I'm surprised this wasn't caught sooner. Excellent post.

nice find buddy! but im almost certain it will be patched out...

EDIT: you can see in the video that you only need a few roaches to block a collosi and that i can get traped.

HAX! D: Being a protoss player I hope this gets fixed. I'm sure if I were a zerg player I wouldn't want it fixed haha.

Well It might be hidden future so we can't know for sure yet will see if its bug or trick, the logic is if roaches burrow and colosi heavy weight on such tiny legs can fall into the tunnel holes that roaches make and get stuck in the ground thats why their AI see where the ground is unstable and wont step on it This at least make protoss have observer with his army... Currently only zerg is quite forced to have one vs terran (ghost banshee) vs toss (dark templar) whats the invisible zerg unit? I hope they make thor unable to move becouse of roach trap
