Not to clog the topic itself we can all exchange opinions here.
Breaching has nothing to do with this. I remember a totally reverse discussion we had on a Queen nesting the pod before marines arriving.Mitchs98 wrote:
Why should this be treated any differently than breaching? Both are an abuse of atmos, so the point is moot. Wyatt is right to bring up aliens breaching into his argument. Aliens breaching can screw over both sides, just as much as controlled phoron fires are.
The aliens main "defence arguement" was that marines in some previous round meta-d and attacked the hive from the point go.
So, it is finding counter arguements and justifying an underhand (and possibly unlawfull) tactic by the "other side atrocities".
In the fire-event in question aliens didnt breach, were not planning on breaching, and would have very likely just overwhelmed the defenders.
Still, I'll answer your question, just to clarify the difference and importance of this issue.
Different effects and counters. Marines have EVA gear, masks and O2, so they have a chance to survive and fight on.
In this case all aliens but 3 died in the explosion or as direct result of such an explosion.
No counter. Deadly effect.
What will stop marines from doing it again?
What will stop aliens from "metaing their meta" and never going up?
