Oh Man, these look very good! The first one looks like a fun mini-game, even a custom. The second one I'm not entirely sure about. I liked the layout, but I didn't really get it. The third map looks superfuncrazytime! I love the tunnel in the middle, a twist off of Reflex's, I assume? All in all, awesome map pack! 11/10, please make more!
It dosn't look bad the tunnel is a copy of reflex so you lost me there.. but your other ideas were not bad and they were pretty soild... 4/5
The first two look alright, but what really caught my eye was the hallway with the coils on Corrosive, that is some fancy interlocking.
The first map is great with a snipers gametype, and all the cover works except if you have a katana, lol. I really enjoyed the last one though, my group of friends played that map the most, and it was the favorite by far. Great gameplay and visually appealing.
