Graphics: Below average.
Cliffside's textures are bad, the buildings are too blocky and the badlands theme it's just way too weak, oh and the lighting is garbage, just way too bright

Gameplay: Slightly above average
The middle of the map is complete crap and it needs serious polishing. Quite deadly sniper sightlines, it's clear that if you want to enjoy this map you need to either go soldier/demo or sniper and maybe scout because going any other class is boring and dull.
Anything but the middle is kinda fun, in fact, holding the tower that is close to middle is very enjoyable

Also Gameplay: The map claims that it has a lots of cliffs yet it only has 4 and 2 of them are not even accesible.
The player clipping its just outright aggresive, there is player clipping where it shouldn't be about 1 out of 3 times, like that big fence that is in the middle, why not just add a wall? even better, why not a building?

Overall: 6/10 Cliffside needs improvement.
