Author's Note: This is my personal experience with Sanctum 2, and thus it is subjective. Feel free to disregard this review as an opinion piece only. I'll also avoid much in the way of personal strategies.
Sanctum 2 is an interesting cross between a FPS and Tower Defense game. It offers the player many choices in building elaborate mazes, multiple characters and perks that offer unique and satisfying builds, and a myriad of towers to choose from. Play with 3 friends, and it threatens to be a serious contender for one of the best co-operative experiences available on the 360.
Right from the get-go, you'll notice there isn't much in the way of a narrative, aside from what's available via short comic strips between missions. While most may choose to skip these optional tidbits of story, those that read through will enjoy a semi-quirky, albeit fun one. But for those that just want to blow up baddies, there's plenty of that too.
Visually, the game is absolutely stunning. Utilizing the Unreal Engine, Sanctum 2 boasts some impressive, and diverse visuals throughout. From beautiful sky-boxes, background set-pieces, weapons and explosions, to the turrets and barriers themselves, look no further. Most maps will feel somewhat claustrophobic in comparison to the impressive vistas, but many offer secret paths, and easter eggs just waiting to be discovered by those that look.
Gameplay-wise, the game is about as complicated as you want to make it. The player has access to 15 turrets, and given resources each wave to build them. Though more often than not, 15 will feel like a limitation in comparison to some of the larger maps throughout the campaign. Barriers are much more abundant, and obviously help to maze off as much of the map as you choose to use.
Enemies will spawn from varying points on the map, in an attempt to destroy the player's core. Their spawns alternate per most waves, in an effort to mix up the player's strategy and turret placement. Much of this is standard-fare per most tower defense games, but with the effective addition of player weapons, often the player can hold off an entire route by themselves.
With friends, you essentially double the fire-power, but also multiply the enemies' health. With 4 people, enemies will hold 8x the health, so planning perks, and towers is of the utmost importance. While the game does hold a steep learning curve when it comes to perks/turrets, the payoff is immensely satisfying once mastered. Some classes are far more "noob-friendly" when first starting out, so experimentation is crucial for what works best for you.
When it comes to difficulty, the game offers 2 choices. Play
with "Feats of Strength", or without. The feats essentially boil down to increasing enemy speed, health, health regeneration, attack ferocity, and taking away player respawns. You might get away with trying a few of these for an added experience boost at the end of a map, it is not recommended that you play with all of these activated unless you have a firm grasp of at least the game's basic concepts.
If you plan on playing the game alone, be prepared for some frustration. While the game certainly is fun alone, the true fun is had when experimenting with friends, and taking on the harder difficulties. The online community is somewhat scarce with Sanctum 2, so having friend(s) is crucial to enjoy the full experience.
Overall, Sanctum 2 is about as good as it gets for co-operative tower defense games on consoles. You'd be hard-pressed to find a more complete game, with both fun and refined gameplay, as well as complex tower-building, and a massive selection of turrets and perks. Grab some friends, build your mazes, and enjoy this great game.
