A few bugs / issues I've noticed while playing this awesome game. Sound bug : When the leveling is doing, the green bar that grows after each game depending on your earnings, if you push the B button before the animation is over, the sound will go on until the next loading screen. When in the Spawning area, sometimes the healing sound of the Support class doesn't play. Some other times, no sound at all play in this area. Support Tower : The Support's Tower sometimes doesn't spawn and the cooldown is reset like it's on the floor but it's not. Blitz : In Blitz, some bots walk in the air or are stuck in the air too. Towers : The upgraded Long Range Towers with Hack may fire in walls in some maps depending on where they are built. I know you can have this problem in GrenAde III and Steel Peel or Power Steel, I don't remember the map's name. In Ammo Mule Arena, if you build Rocket Tower and upgrade them with Hack, they'll fire at long range but the Rocket will be stopped by your own bots, not damaging them, but wasting the build and the hack because it doesn't affect the enemy bots. I'm not sure it's a real issue since here it just may be considered as the line of sight. While playing, I experienced these bugs only a few times compared to the number of hours I've already played so it's no big deal, really. I also had 2 freezes, one at the launch of the intro cinematic, for the other one it freezed during the game at the spawning area, I could pause, watch the scores but not move. It also crashed one time with no error message. I've played many hours yesterday but only the Support Class, overall, the game seems very well balanced to me and the maps are really cool to play. It's even better than what I expected... and I've been waiting for this game a long time . I hope this will help, sorry if some issues have already been described in other posts. Thanks Uber for this great game.
The map you are thinking of is Steel Peel. This is intended, they wanted a map that wasn't affected by artillery (i.e. Long Shots). The purposely put walls in the way, so building them in Steel Peel is a waste. Gap Shots are almost just as effected, but since they're mobile they have a better chance at not hitting a wall.
