Feels like a cheap hollywood flick. Things happen the way they do because plot needs it, not because it makes sense. Marines can't use 'armor piercing bullets' inside the ship because 'they don't want marines to blow half the ship into oblivion', yet marines get pushed back because the sorry excuse of a bullet they are allowed to use can't even penetrate the bugs carapace. They have to shoot at the bugs open mouth or the joints to even do damage! Yeah right... With such redundant weapons ofc the things don't go well. Marines are killed in droves and they are being pushed back so bad, they start using grenades that throw around tungsten balls that turn into plasma and can pierce the bugs and leave the hull of the ship riddled with holes. The Captain is informed that the situation is getting desperate and %80 of the defenders in one of the engineering section is dead, so they ask to use the armor piercing bullets, but NOOOO. It is not allowed, keep using grenades good chaps and leave the ship riddled with holes haha! Oh also, keep being meat shields haha! Enjoy getting eaten alive by bugs hahaha! What a great idea! They don't even trust their own marines to use armor piercing bullets because 'it might pierce into the reactor core and blow the ship'. Seriously? So they use grenades which can do much worse instead? The notion of armor piercing bullets going through the walls and reaching the reactor is already ridiculous enough, a reactor room shouldn't be so unprotected, but even if such a worry is real, why would they use such powerful grenades then? Their 'ceramic bullets' that don't pierce the hull of the ship also can't pierce the bugs carapace. So by logic, this grenade that sends tungsten plasma projectiles which can pierce the bugs carapace, can also pierce the hull of the ship! If not, why would they make the ceramic bullets so useless? If the grenade doesn't pierce the hull, but can pierce the bugs, then why would they not make a bullet that can actually work just as well as the grenade!? See, this is the logic hole i'm talking about! Anyways, because they are not allowed to use armor piercing bullets and because they are slow at clearing out the bugs that breached into the ship, the bugs reach a conduit and everything goos BOOM. Ship is done for. All because they were afraid their own marines can't shoot straight and the somehow 'so overpowered armor piercing bullets could pierce the reactor'. Sigh... The best way to describe what i'm feeling right now would be 'feels like a cheap hollywood flick'. Disappointing. Very disappointing...
