Yeah, I think 'optional' implies that you don't need to do them. ¬_¬ Depends if you have to go out of your way to find them (Dead space isn't known for it's open-world-ness) or if you're assigned them during your missions like Assassin's Creed.

Side quests in a Dead Space game?! Interest piqued.

There's always the danger that these missions are boring "fetch-quests", but I sure hope this isn't the case. Interested in how this is going to turn out. Arh, February still seems so far away :(

assuming we can go off mission course for optional side missions, bigger mappage to explore :)

Blegh, they're a pain to do alone and some require a co-op partner which I don't (yet) have. But seriously, I don't need even 1/3 of the med & statis packs in the main missions as I do in the optional ones. Constant huge hordes and those bigger fellas with pickaxes or something aren't helping at all.

Easy way to destroy people, set up a double shotgun, you can almost max all the stats with a fully done heavy elite frame. -OR- you can go double bolus gun, one normal fire, one 'land mine' fire. both are so powerful, I pretty much beat the whole game just using the shotty, I don't like the bolus but people have stated how good it is.

Do you have to do all of the side missions in one play-though? I can't find this answer, anywhere. I'm on my 2nd play-through and did some side missions the first time and would rather not have to do them again.

@Angel4711 I don't believe that they do. But your new game + file should on a different slot from your first playthrough. You can load it up and replay a chapter, it should tell you what you have missed and you can collect all the collectibles or replay the optional missions.

@12 It IS on one playthrough, but remember you can replay chapters at any time (and if you picked up the item leading to the mission you can choose the optional mission from "chapter select"). I did my first playthrough solo, then, on new game +, did only the main story and co-op missions. The achievement didn't pop and under "progress & unlocks" it shows those optional missions I missed during my second playthrough as incomplete.

To get this achievement, do you have to do the Co-op missions too? Or can you just do all the solo missions and get it?

Comment #16 by Eleriel

#15.
yeah, you have to do the co-op missions too.
(the only unlockables you can get by singleplayer alone are the difficulties, the unitology-, S.C.A.F.-, and Alien Artifacts).

Comment #17 by Eleriel
Saturday, February 16, 2013 @ 12:38:25 PM

#14 new game+ is considered a whole new playthrough.
the only thing that carries over are the collectibles you've discovered (and weapons and resources)

If you do all the solo optional missions in Classic Mode, you do NOT need to do the co-op missions in order to get the achievement.

I can personally confirm this, as mine popped last night in Classic.

Comment #23 by GMFRK
Wednesday, March 06, 2013 @ 04:27:33 PM

I can confirm with #22 seeing as classic is single player only so you only have to do a total of 7 missions instead of the 10 (think it was 10)

I actually didn't know about this till I noticed it randomly pop up when I was completing the disposal mission (and then there were 3 of those things, oh god...)

Does anyone else want to do this coop with me?

Comment #25 by ParadoxReal8
Tuesday, May 14, 2013 @ 09:47:26 PM

I got the achievement for all coop-mission but the last one on mission 14 did not enter...
Is it glitched?
Anyway, i'll redo it even if it is a pain in the ass.
Espacially when the partner put it in impossible at any second.
My Gamertag is in my name... :p

If you can get this achievement in Classic mode, can you also get the collectible achievements in Classic? Like to bypass the co-op only collectibles?
