The first is Jump Jets, the second is Power Detonate. There are two other important upgrades you'll need to help you win the fight. This means that every time you put research into Training, your engineers become tougher, and their lasers more powerful. The best thing about engineers is that almost all of the land unit upgrades on the tech tree also apply to them. Then order those engineers to buff the new factory. By this stage you should have enough resources to start building more land factories as well. Throw down a few anti-air turrets and invest in Rate of Fire and Training on the structure tree and you'll be able to repel most air assaults. If your enemy has gone for air superiority you'll want to grow your force of engineers under an umbrella of protective laser fire. With increased health, regeneration and repair rate, engineers can heave each other back to full health within seconds of a firefight ending. Engineers do several things automatically if you leave them idle: they shoot anything that comes in range, they vaccum up the remains of anything they kill and, when there's nothing better to do, they heal each other. The repair upgrade will turn your engineers into a robust defensive force. Next you'll want to research Regeneration, Health and Repair Rate. Your engineers are armed and barely dangerous, but you should have enough to repel any early attacks the AI throws your way.
