Summary: The tower defense genre recently got a nice boost in novelty with the release of Anomaly: Warzone Earth , which turned the genre on its head, and now we have Sanctum ; a game that puts the player inside tower defense. Other than that both games involve towers though, they are really nothing alike.
Conclusion: It just feels like so many of the design decisions in Sanctum 2 were arbitrary additions as opposed to carefully through-out improvements on the design of the first game. A while back on Twitter I was saying how indie developers should iterate on their games more often, rather than making a thing that is flawed in some way (as everything always is) and then just abandoning it and its ideas.
Conclusion: Although Sanctum 2 is the sequel to one of the first FPS-tower defense hybrid games to come into existence, Sanctum 2 feels a bit left behind as other games of this hybrid genre have improved upon it in ways Sanctum 2 has not.
Pros: Unique graphical style with a sort of manga feel, Different characters to play as cater to different playing styles, Plenty of options in terms of weapons, towers, and perks
Cons: Not much new here that other games of this type haven’t already improved on, Needed information for playing the game is sometimes held back, Gets to be difficult without other players backing you up
Summary: It looks like Sanctum and it sounds like Sanctum, but it plays totally differently. While the more devoted fans of the first game might take issue with a lot of the changes, and while it doesn't match up to that game's heights, there's still a lot to enjoy in Sanctum 2.
Excerpt: Against an army of alien invaders, the trusty turret has always got your back. Like its predecessor, Sanctum 2 is an enjoyable blend of first-person shooting and tower-defense-style strategy. Instead of watching passively as your towers do all the dirty work, you get to dive into the action and sow carnage alongside them. Both games execute this concept well, but Sanctum 2 has far more content than its small-scale predecessor.
Pros: Unique and balanced mix of tower defense and first-person shooting, Large arsenal and difficulty modifiers encourage replay, Tackle each challenge with up to three friends online.
Excerpt: There are never enough points for all the weapons I want and never enough building blocks to make sure that enemies have a hard time reaching my core. The paragraph above sums up my feelings before starting each new wave battle in Sanctum 2 and also explains why the game is an interesting mix of tower defense and fi...
Conclusion: Concept: Combine tower defense and FPS combat to outsmart baddies trying to damage a precious core
Graphics: The crisp and clear graphics, interesting level structures, and unique character models stand out, but some backdrops could be more creative
Sound: Sound bites for characters add personality and the music creates tension, but it’s nothing out of the ordinary
Playability: The rules and controls are easy to learn.
