Best Tower Defense Game Ever

I got this game for free, as a part of GMG Welcome Pack. At first I thought this is just another stupid tower defense game. But I decided to try it out because everyone was like "Oh what a great game, I'll play it forever". And, when I played it for the first time, I immediately fell in love with it. Now, I'm like "Oh what a great game, I'll play it forever".


FPS Tower defense???

Have you been addicted for many hours to Desktop Tower Defense? Or perhaps you love those really long CS:GO marathons with your friends... Either way, I'm almost certain you know what a First Person Shooter and a Tower Defense game are, and you probably think they haven't got anything to do with eachother... Well, you're wrong. Sanctum exists. In Sanctum you must protect your core by placing different towers and weapons across the map, but when the horde arrives, you bring out your personal arsenal and the creature annihilation begins. And now for the icing on the cake: Co-Op! Bring your friends in! With a 2-4 person Co-Op you can make the game surprisingly better and have 2-4 times more fun.


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.
