I wasn't all that bugged how it appeared as just a mission out of no where. But I did think it was weird how on the loading screen there wasn't any speech or something (especially for all the hype that surrounded this weapon) and I was a bit confused why the enemies spawned in a straight line like that. To be honest I was thinking the way they were spawning was of some importance, cause it was a mix of taken and regular hive. Thought there was a hidden pattern but idk
