Pros
Pro Challenging gameplay
Orcs Must Die is fairly light on the third-person shooter elements; while shooting is a big element of the game, it is somewhat barebones in its design. Most of the fun comes from its tower defense elements, where players must carefully plan trap zones in order to receive the maximum amount of points, which influences how much money they receive, which determines how many and what kind of traps they can use.
Pro Offers heaps of replayability
The game has many maps, a ranking system, a wide variety of items that can change each match significantly. Players may not be able to master a map right away, earning all of the rewards for completion, but after they earn more gear, they can return to try again.
Cons
Con Gets repetitive over time
Actually since the game is perfection based (meaning you'll want to redo areas for better scoring) and has plenty of included plus DLC maps you can play OMD2 for quite a while and it will seem fresh. The difference in difficulty levels also can refresh the same map since varying levels release different type of enemies.
