Handy With Tools

Handy with Tools is an achievement in Halo Wars that is unlocked when you repair the Power Core in under four minutes on mission 12.

Tips

 * Build as many Cyclopses as you can. Hornets can do the repair too, however they require more resorces to build. So just build Cyclopses.
 * You can use the healing and repair function of the Spirit of Fire for the energy core.
 * Building too much of other units will lengthen the time. In fact the units to start with is quite enough. Besides, you'll need resorces to build Cyclops and the heal and repair can easily heal your units.
 * It is possible to let all your units survive using heal and repair on the energy core while your Cyclops and Hornets repair it.
 * On higher difficulties, you may need your Spartan-IIs to hijack enemy vehicles. It is very useful, since you will be focusing your resorces on building Cyclops and the heal and repair function.
