There is just as much reason to drop chemical OB on LZ as there is to drop IFF sentries who shoot anyone who isnât a marine.
Rightfully so survivor is low on dev priority. For a very good reason. Even the slightest change fucks somebody up, it is always marines in the long run, but short term it can go both xenos and marines.
No armor one-shot neuro existed because survivors. Trucks nerfed because survivors. Shit groundside nerfed because survivors.
Every single tool, every single change, anything you do to change survivors fucks xenos, or marines in some way, directly, or indirectly.
From the lore/IRL standpoint it makes a bit of sense, colony goes silent and only sends distress signal, nothing else, no one trying to reach anyone in space, just poof. Suspicious as hell, be it CLF, false-flag UPP, or even xenos.
There is a small problem that it is just gas. Like come on, wear closed air circulation suit and no matter how good that gas is, it is not boiler acid gas, so you are fine sit in LZ waiting for marines. Or rig LZ to explode before you send distress, then they can gas it all they want and you can still blow them up with minimal costs.
UA could just instruct colonists about their practices of gassing LZs, so you are not supposed to stand there.
Among other things, those are reasons why I always said to fuck survivors in terms of balance and gameplay. It is a masochistic role for guys who think they are hot shit, to give xenos something to do for those first 20 minutes, not a legitemate role that has to be entertained and given much attention to have fun. PFCs and xenos are roles that should be treated like that.
You want to know my idea how to make surv gameplay better? Buff roaming in exchange for that PR. But buff it in a smart way that wonât impact marines and wonât fuck up xenos too much.
Make them invisible to xeno thermals. And by that I mean make survivors invisible for xenos trough walls, but only for like first 25-30 minutes of a round.
Then you can emulate Alien: Isolation when playing surv, where hiding, distracting and running away is the name of a game. Add makeshift motion detector, like the one they made in first movie, like out of two proximity sensors and some other crap, one that is super quiet, but has no IFF, so pings at anything.
That would be much cooler and different from either running and gunning around the colony, or just holding one spot.
