The premise of Orczz is that the kingdom of Whiteleaf is under attack from a massive horde of savage Orcs from across the sea. Their goal is to steal the kingdom’s supply of mead, “the 
delicious honey wine.” The player must rally the diminished forces of the Knights of the Mug and mount a defense. At its core, the game is almost identical to Plants Vs. Zombies. The goal is to prevent the Orcs from reaching the castle and stealing the mead. Like PvZ, the Orcs advance from right to left in designated lanes. The player must place knights in the lanes to kill the orcs. A counter in the bottom right of the screen indicates how long the player must survive. Once it reaches zero, and all the remaining Orcs are beaten, the level ends and the player advances. However, the Orcs on screen will continue to increase in number and strength as the counter ticks down.
At first glance Orczz looks just like PvZ. The same goes for the second and third.
Orczz does manage to distinguish itself from PvZ in a number of subtle ways. PvZ, for example, places a lawnmower at the end of each lane to serve as a one-time insurance policy should the zombies break through that lane’s defenses. Orczz does the same thing only it uses a catapult. Unlike the PvZ lawnmower, the catapults must me used manually. To launch a projectile, the player must hold down the left mouse button over the catapult to prime it and then release the button to fire. The distance that the projectile travels is determined by the angle of the catapult prior to releasing the left mouse button. The catapult’s projectile is strong enough to kill most Orcs and can sometimes take out multiple Orcs with a single hit. Proper catapult use is essential to the game and requires a fair amount of skill to master. They do, however take a long time to reload so missing the target can be costly. Once an Orc reaches a catapult it is destroyed and cannot be rebuilt. The attacking Orc is killed in the process, but if there are more behind him then it’s pretty much game over. I think the catapults add some level of enjoyment to the game, but they can also be the source of much frustration.
