I Realized when throwing grenade Manuel not saying "grenade" is this a bug?

I feel like this bank lobby section is a little excessive with the zombie spawn rate in the current state, it's a very high rate of non-stop spawning zombies that aren't easily held off by smaller numbers of players.

The level is just way too dark, literally cant see anything. Nobody will play story mode while this game has such a cheap tactic of having pitch black darkness.

I've noticed over the last couple months I no longer have the option to select bots in Offline mode. I'm not sure if I'm just missing something, but I distinctly remember there being a setting in the host menu to enable bots, alongside their number and skill, but this is no longer possible. Do I have to be connected to the internet to play with bots?...

Who would have thought extremely claustrophic linear spaces was a recipe for frustration in a zombie shooter. Absolute nuisance of a map
