Sanctum is an unassuming game. It is clunky from the visual perspective and tutorialization. It isn't particularly satisfying or creative in its towers or weapons. There isn't a strong sense of style or music. But this game does scratch that 3D tower defense itch really well, criminally well for how underplayed it is (Less than 2% of players have beaten the final level despite it being quite satisfying). The maze building offers the most freedom in the genre I have seen, the experimentation and min-maxing is an option for players, and you get a hefty amount of money every level to keep your decision making involved.

If you want more Orcs Must Die, this game is fantastic. If you bounced off Orcs Must Die for the sappers and fantasy aesthetic, this is the game for you. Otherwise, this game is just gonna awkwardly stand behind Orcs Must Die.

Sanctum is a strategy/FPS hybrid game with tower defense tied in, complimented by its exciting and catchy sci-fi soundtrack and awesome environments.

In Sanctum, you play as a soldier known as Autumn Skye, and you must defend The Core, the power source for all of your towers and for your entire base. Aliens of different forms will come and attempt to attack it, and attack you and your friends. Each enemy has different strategies of attacking, and each one has different weak-spots, where hits will do more damage than the hits would on the other parts of their bodies. Some of these enemies are airborne, and will attack from above, and some will attack ground-level.

There are 16 maps in the base-game Sanctum, and each have different amounts of space for your tower bases. You can arrange them however you like, and you and your friends must build a maze to make it so that the aliens, known as the Lumes, will have the hardest time possible attempting their reach to your Core. You must use your resources to build new towers, upgrade old towers, and upgrade your weapons.

Sanctum is a fun game to play with friends, or in single-player alike, and the variation to the enemies, weapons, and towers is pretty cool. I would recommend this game to anyone who enjoys strategy games, FPS games, and tower defense games, as well as those who like sci-fi themes. ^.^

Sanctum is what you would get if Defense Grid: The Awakening and Unreal Tournament had a baby. Tragically, this game is less than the sum of its parts, leaving it feeling merely okay. Some bizarre design choices and an interface that tells you next to nothing valuable make this game far more frustrating than it needs to be. The gameplay is alright, but it wasn't enough to keep me coming back for more.
