Handy With Tools

Handy with Tools is an achievement in Halo Wars that is unlocked when the player repairs the Power Core in under four minutes on the twelfth mission.

Tips

 * Build as many Cyclopses as you can. Hornets can do the repair too, however they require more resources to build.
 * You can use the healing and repair function of the Spirit of Fire for the energy core.
 * Building too many other units will lengthen the time taken. In fact, the units to start with is quite enough. You'll need resources 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, since you will be focusing your resources on building Cyclops and the heal and repair function.
