Good little map, but I do wish there were at least some ammo spawns.

I use this map for aim training while playing solo offline with CD. I don't use the barriers much though (except on a boss wave, but the map is not a boss training map anyway), as I perceive that it teaches you to ignore EDARs and husks at long range, which is often deadly in real gameplay. Unfortunately, because of either sound channels saturation or because they are too far or who knows why else, sometimes husk charges come silently, without the spinning up sound, which makes it extremely annoying, but it seems to be a game problem nobody is looking to fix. My solution to this is not to get touched by trash so I always have a health pool deep enough to allow me to survive a direct husk projectile hit.
