Lunar was designed first and foremost to be a fast paced and have an aggressive play style and forces the use of tactical play through weapon placement, claustrophobic interiors and open world exteriors. Adjusting play style dependant on your weapon inventory. Be it sniping in the outdoor areas or running amok with the flak cannon in the tight corridors.
Constraint is a small one on one map with a very free flowing play style and height elevation to allow a well timed ambush of your prey, but be careful as those in the lower depths are far from defenses with the flak cannon being placed in the underbelly of the map
