@r3d_belmont456 Thank you for the map! Mt. Erebus is neat indeed. I didn't finish it. I wanted to but the barrel revenant tunnels started pissing me off. So starting with that the real issues I have are the revenants that come in from across a line of barrels with the chance to blow them up before they come around to me. The other issue is that the teleporter going into and out of that barrel challenge room is in the same direction of the teleporter so the monsters left alive in the main area of the map gather in the same corner so even if I do pass it I just get trapped by them when leaving. This is of course because I want to do that room first thing because it's the most difficult part of the map, hesitating to call it challenging due to the prevalence of RNG and dying to it at any point later on in the map feels like an instant death trap. It's not the most polished thing but I do like it since it is at least original and earnest effort went into it. Instead of another green armor a blue armor would be appreciated instead for a reward and wouldn't be so samey. Since the room is mostly just barrels it could easily do with some more detail. Most of the map is pretty bare-bones looking, lacking lighting variation and (decoration) detail so it feels pretty vanilla too when even a few simple but effective touches would do nicely to spice it up and not feel so boxy. Remember that it's your map and that bringing things to the point where you're comfortable and satisfied with it matters most.
The map is kind of buggy and glitchy in that my weapons and collision hit invisible walls in the middle of the map in random areas. Things probably got screwy in development so my duct-tape answer to fix that is to open a new map and copy and paste what you've already made into it to start over in that sense. I could write more but it's just issue with the basic visuals and lack of polish. More preferential desires would be wanting a plasma rifle to stun-lock the spider mastermind so I don't have to wait for the crusher to kill it and risk dying trying to help as I did.
