Everyone knows how important Advanced Sensors are, and without the advanced engineering module... you’re asking for trouble. You can still maintain an eye on your workers without it, but that is very risky against vets. It takes at least 245 seconds before the enemy can even build them (without QUANTUM upgrades). Even if he builds both weapons and engineering and hangar right from the beginning. The REAL concern lies with the crystal bombs. The crystals are a much better target for the mimics, and require fewer ships to deliver more damage to your workers. On a map like Close Quarters, Be sure to ram or missile the crystals before you send in your workers. You may find a swarm of mimics heading in towards your RU op, but it is a rare event to see a wave of mimics before the 5 minute mark (not a wave to be worried about anyway :\ ).
Micro-ship construction is another favorite. Aside from leeching the enemy processor or building a wall of sentinels to defend your own, this is one of the more powerful technologies in the game. Not much can contend with 15 hive frigates with fighter support. ( and... 90 swarmers can really slow down your frame-rate, so be careful )
Overall, this module doesn't really need to be rushed, but it sure is handy ASAP.
*Crystal processing is unlocked by researching salvaging technology in the Engineering module first.
