Sanctum 2 is free on the Humble Store

For a limited time, Sanctum 2 will be available for free on the Humble Store, offering PC gamers a free Steam key for the title which will allow them to play the game on Windows, Mac OS and Linux. 

Sanctum 2 is a tower defence FPS hybrid, offering users the create and defend an area using both FPS mechanics and by building walls and defensive towers. This game can be played alone or with up to four friends. 

 

   Sanctum 2 is the sequel to the world’s first Tower Defense/FPS hybrid game. Pick from four unique character classes and protect the Core! Outfit your character exactly the way you want through the new and extensive customization system. Choose your own loadout of towers, weapons and perks, but choose wisely because you are humanity’s last defense against the unrelenting hordes set out to destroy it.

Sanctum 2 is a new game completely rebuilt from the ground up using community feedback and innovative design to really push the bar of what an indie studio can do.

In Sanctum 2, you will utilize elements from multiple gameplay genres to succeed. Construct towers and walls during the building phase before the enemies attack, then jump into the fray and blast everything to pieces in FPS mode. You can progress through the single-player campaign yourself, or play with up to four friends in co-op!
