Hello they call me the idea guy.
Remember in the first film when the larva evolved into a drone and it shed its skin? We should add skin shedding for xenos when they evolve. Nothing else, just a shedded skin on the ground.
Remember in the first film where Dallas gets nabbed in the air shaft but there’s no blood. There’s a scene in the special edition where he and Brett are being turned into eggs. I think it would be cool if drones could inject perma corpses and turn them into eggs. I know we have the egg morpher but only burst corpses can be used. This would give a way for xenos to deny gear and tech points, and reinforce the horror that they are. To avoid xenos from meta gaming when a marine is perma, and to give marines time to extract the body, I think it should be sometime after the corpses actually permas - maybe like ~15min. Imagine breaking a siege and walking back to where all your friends are only to see them halfway turned into eggs.
