The Type-25 DER is a battery-powered directed energy weapon capable of fully automatic fire. The exact mechanism by which it functions is currently under investigation.


Up until just recently the Plasma Rifle had been the primary weapon of the Covenant’s officer corps 2. The weapon has a power output of 100~150 Kv@2~3 dA.

It has been widely noted that the disparity in the effective combat range between Covenant short and long arms are much greater than those of the UNSC—this is also reflected in the Covenant’s combat doctrine: destroy enemy morale with harassing fire from distant or hidden snipers and intimate exposure to the alien-ness of their infantry.


“These things are huge—but I guess the Elites are, too—so it sort’a makes sense.”

“[The Type-25 DER] has no recoil to speak of; it tears the ____ out of shields and you can shoot the thing all day long—it is on the heavy side though.”

“I realize that it uses a battery instead of a magazine, but nobody has figured out how to swap it or recharge it yet? Don’t we have scientists working for us or something?”

“It’s got no sightline, it’s awkward to hold, and if it overheats it’ll cook the hair right off of your wrists.”

“You know, it looks delicate and so you feel like you need to hold it kind’a gingerly—but then you see an Elite crack in a Bravo Kilo’s head with one—thing’s are built tough.”

“Yeah, and I’ve seen some [Elites] swinging two of them around like it was nothing—scary ____.”
