If the Attackers put up the walls at the end of the map you, as defender, have no idea what to do to get them down.
Generally, you have no clue what you can do to help your team (build extra stuff), you just kinda fall upon construction/destruction points by accident while you learn the map.
Boring drudgery.
Isn’t that the case for every map though? First time I was on Terminal, I didn’t have the slightest clue what to do. Same thing for Trainyard. While Underground is no exception, I don’t think it is worse in that aspects than the other maps - it just needs some time to get used to it, but there’s not too many options you can construct/sabotage anyway…
If it’s the wall that I’m thinking of, it does ruin some of the gameplay for that part of the map. From what I’ve played of the game, the attackers raise that wall by constructing something in the right control room filled with TV’s and it goes down by the defenders blowing it up.
When the wall is up, it completely blocks the last objective from the defenders spawn and only leaves the path leading to the control room open, a room that isn’t all that easy to spot. I would suggest making the control room path more visible so it stands out much more as a path to use as well as adding another way around the walls if they end up being constructed.
you can still use the pipe over the walls though
I kinda like it the way it is (not the map overall, but that part)
I’m pretty sure you can also just double jump over the walls, at least as a fast class.
