Solution to Cheese

This puzzle describes several Starcraft 2 tactics, as described by a newbie observing them performed by the other player. The only problem is that they've been expressed via incomprehensible Zerg noises.

In translation, they are:

• Note to self: learn to watch for the enemy builder unit outside my base. There's no way to stop the attack once they start warping in buildings on the high ground.
• All of a sudden, a bunch of crawling things came in and razed my buildings like *that*.
• I showed up in his base and counted - enemy had 11 workers and only one overlord. What.
• This one seemed reasonable, but then I saw he had taken 4 bases way earlier than he could defend any of them.
• I laughed when the command center landed in my base. I stopped laughing when it finished changing and blew my entire main to bits.

The tactics are:

• Cannon Rush
• Roach Rush
• Extractor Trick
• Economic Cheese
• Planetary Fortress Rush

The first letter of each of these tactics spells out the answer, CREEP.
