'Burn them all' achievement

[The Traveler]

I beating most of the... well, at least the SP achievements. That Burn them all achievement says use in pone chapter only plasma weapons. That means I can only use the 'plasma' titled ranged weapons? Or any melee weapon count as a 'plasma'? i knoe, stupid question, but I'm not home at the Warhammer universe.

Only plasma weapons, meaning, plasma pistol or plasma rifle.

=TaT=Cpl. Panzerlied is absolutely right, only the plasma pistol or plasma rifle count for this achievement. Melee doesn't count at all (so neither to executions!).

The best place to get this achievement is in chapter 10 ("House of Secrets") as you will mostly only have to deal with turrets there. Only at the very end of the chapter will you encounter a couple of enemies which should be easy to deal with.

Thanks the help, guys. I made the other weapon achievements. So no melle, no execution(!) and guess no grenade. Maybe I'll try on Normal difficulty.

Ram kills also no permitted?

You're welcome. Personally I did all of those single player weapon achievements on easy difficulty, after finishing the campaign on normal. Doing them on easy saves you a lot of hassle. There's no real added benefit to doing these particular achievements (single player weapons) on normal or hard - unless you enjoy the challenge, of course.

You're right, grenade kills are also out of the question. I'm not sure, but I think ram kills are also not permitted. Never tested it myself. I'd play it safe and just stick with the plasma pistol. Monsters killed by your party (Sidonus, Leandros and the Inquisitor depending on what chapter you try) do count towards the achievement - it's only captain Titus that needs to get solely plasma kills.

The enemies at the very end of chapter 10 should be easy to deal with - iirc it's gretchins, regular ork boys, a few bomb squigs and a couple of shoota boys. The rest of chapter 10 is weapon turrets (machine gun and rocket) and is easy to do with a plasma pistol. Most other chapters would be rather more difficult to unlock this achievement.

Good luck!
