Ok ladies and gents, so we got a big problem on our hands in the shape of a literal army of Husks. 2000 might seem excessive, but fuck it, who doesn't like high stakes.
So the players on the infiltration team now have to play nursemaid to the scientists, while fighting their way through waves of Husks on their way to the Assault teams position, while the Assault team have to finish off the turrets, save Ellis (if they want to. They could choose to let him die!) while also dealing with whatever packs of Husks that come screaming from that tunnel before the infiltration team. Think Nazi Zombie mode in COD.
@POOHEAD189 Sorry I couldn't fold your last contribution more effectively into the post. Between Ark and Vella's barrier, there really wasn't many options I could see there to make Skarr's efforts more effective. However I'm thinking, and if
@MrDidact is agreeable, we could let Skarr have access to his full range of Biotic powers again, like you planned originally. It doesn't look like AquaAzura is coming back with her Asari, so that opens the Biotic role up. Gives you a bit more versatility in play.
