Background Lore

"MACE is an incredibly unorthodox division within the Combine. They utilise a highly experimental cloaking device in order to infiltrate behind Resistance lines and perform flanking maneuvers near-impossible without the aid of such technology. How the technology functions is unknown, as is any effect it may have on those that use it. There exists a small sum of controversy amongst Union command elements on allowing what is essentially nothing more than an elite MPF division such advanced technology. 

Well founded in their distrust, and to the ire of those very same Command elements, the Resistance have managed to find ways to disable and reprogram the cloaking system for their own benefit. They’ve been given to Resistance Spectre Units after the discontinuation of the disguising technology, making MACE and SU a sort of equal for a short period of time. However, this technology for the Lambda Core has been reverted back to the disguise kit."

How to counter

• Uncloaking MACE will produce a distinct sound. Pay attention to their uncloaking sound and react quickly to avoid being killed by one. Normally they tend to uncloak behind rebels.

• Military Police members who decide to interrogate a captured Combine should have RU or LVET Commando as guards, as they can directly shield the captured unit or block entry ways.

• Technicians deploying air vehicles should always keep them as far from the ground as possible.
