A very good game!

When I was young I was searching on the internet for tower defense games, but then I found this one. With Sanctum you can build your towers and fight with FPS together! The multiplayer function is also good, as I love multiplayer. You can build towers on maps with friends and defeat all the enemies.

You don't need a high end pc for this game, I am playing with i3 4gb ram, and sometimes laggy, but most of the time it's very good to play.


Good game, better with friends

Sanctum is a tower defense in which you play a character owning his own weapons and particularity. It is not a basic tower defense, you have to make the choice to upgrade your tower, make other towers or to upgrade your weapon. If you make the wrong choice it can be quite hard to defeat the level, at least in solo.

For the multiplayer it's funnier, the choice that you make have less impact in the game so you can enjoy more it. Playing with friends is always better.

It is a bit different from Sanctum 2, the strategy here has a bigger place. If you liked Sanctum 2 you will also like Sanctum (1) if you prefered placing towers.


Enjoyed this more than I expected

This game does not have the most stellar graphics, but it is certainly made up for in gameplay. How this game works is that it is a tower defense, and as you would expect you earn money which you spend to build towers. What makes it unique, however, is that it is also an fps. What this means is basically that you yourself are a tower among others! I must admit though, playing through did get boring at points, but i would just stop and pick it back up at another time. What improves this game is definitely playing it co-op with a friend, as it makes the overall experience much more enjoyable and much less annoying.


Power Defence

An innovative twist on the tower defence genre, Sanctum puts you in the both the role of construction overlord, and hired gun.

Waves of enemies are coming for your base, and it's your job to stop them. Place a maze of blocks, traps and weapons for your enemies to navigate, and then take them out with your own weapons skill (and a variety of guns!). Spend money earned from crushing your antagonists to either buff your defences, or upgrade your guns into ridiculous killing appliances.

Fun alone, but great fun with friends, Sanctum is the sort of innovation we'd all love to see more of.


OK on your own, good with friends.

Sanctum is a first person tower defence game, it's a great combination which I hadn't experienced before, mixing up the strategy and planning of classic tower defence games with the action packed fast pace of a first person shooter. The graphics are good, with a nice art style allowing for a decent amount of contrast, although at times it can get a little muddy with lots of enemies all packed together. There's a good range of weapons for your character, as well as the different towers you can build. Since you choose the route the enemies take by building walls, it allows for a good amount of replayability. It really shines when you play it with friends though, allowing for a really fun experience as you frantically try to help each other out as you try to hold back the waves of spawning enemies.
