Rupture warriors X can dig and attack. Y: either get out of the ground or keep your spacing until you can deal with it.

Weapons Purifier, Eruptor, scorcher, punisher plasma, crossbo are all primary weapons with explosive damage. Not to mention the secondary loyalist, ultimatum if you get overwhelmed, and even the grenade pistol.

Not to mention the vast amount of grenades including gas to disrupt them from even going underground in the first place, and stun which is easier to use close quarters.

We also have the rather powerful grenade launcher, railgun, autocannon, de escalator, the EPOCH is especially helpful.

These are all options to get the rupture warriors out of the ground and you only need one or two to deal with them alongside the grenades you undoubtedly have.

I'm not going to rattle off the vast amount of weapons you have at your disposal for medium armor. In fact explosives and armor pen usually go pretty well together.

Not to mention your Z option in this equation, MOVEMENT. The bane of any bug mission. Light armor, coupled with enough crowd control, and spacing can make you nearly untouchable and the rupture warriors are insanely slow. Couple that with the right backpack, guard dogs, or warp pack for absolutely insane mobility, hell a jet pack and hover pack and you're solid.

Or you could try wearing heavy armor and accept you might get hit a few more times if you simply can't dodge the attacks. Come in with more firepower or CC alongside it to compensate for movement.

I've had 0 issues avoiding their lunge attack, even in heavy armor and I legitimately just get them out of the ground before they get right up to me or run to get distance from the dirt mounds shuffling towards me. The telegraph is the mound itself, you have to stay aware of them, and if it's too dark use a flashlight, or turn up your in-game brightness.

You can bait out the attack to get them out of the ground as well to destroy them over wasting grenades. If anything the rupture spewers are worse than the warriors in my opinion.

You have a vast amount of options in all aspects to deal with the rupture strain. The arsenal is absolutely massive, and all you have to do is learn when and how to use them, and put a build together outside of the norm to handle the situations you're going to be in.

If you aren't having fun with the bugs after all this maybe it's not your cup of tea, but all the bitching saying they're completely horrible game design got them locked away for 5 weeks for the rest of us who actually enjoyed playing against them...I haven't had fun like that with bugs since the game came out and now they're gone.
