Here's the only problem with a Cryo Glitch. In order for the Glitch to be of no help as others say, you MUST rush the enemy. If you don't rush, you are MASSIVELY disadvantaged. If you choose to boom or turtle, you will get SMASHED by a full wave of T4 units when you aren't ready.

The issue is not the Cryo glitch's unstoppability (because it can be stopped). It lies in the fact that, in order to halt it, you absolutely must follow a single strategy, and that is to rush the enemy.
