From Strategyinformer.com: "Naturally the level design part of a game such as Sanctum is incredibly important. That’s why it has to be even better in Sanctum 2! During the development of Sanctum 2, we’ve made design decisions that make the game much more action packed than Sanctum 1. For example, enemies can now attack the player, and they can reach the player even if they are standing on the walls. Because of this, we felt that we also needed expand on the complexity of the level design as well, as to keep the strategic elements on par with the action-based ones".
