Customer notes

Requires Sanctum (base game) to play this pack


This map pack adds four action packed levels to your game!


  • Things haven't gone quite as planned. What begun as a minor annoyance has since blossomed into a full-fledged threat. In spite of the military's questionable (Four soldiers? Really? Was there a budget cut?) efforts, Elysion One has been swarmed over by the mysterious aliens that Skye first encounters. Fortunately, however, the aliens have yet to discover that the terrified bipedal creatures running about underfoot are edible.

    Yet.. It's the aftermath of the alien invasion but there's still time. Skye and her friends must keep what remains of Elysion One safe while reconstruction begins in earnest. Can you survive the Aftermath or will the extra-terrestrials finally discover that the populace is crunchy and tastes good with ketchup?


  • In spite of the military's best, under-funded efforts, Elysion One has been overrun. Things couldn't possibly get any worse, right? Wrong. For the first time in recorded history, Elysion One was hit by an earthquake, an unfortunate catastrophe that left reclamation efforts at a stand-still. But that's not what has everyone worried. It's the aftershocks. They're happening with surprising regularity. More disturbingly, they seem to be getting more intense. Will this build into another earthquake? Some say yes while others claim that it might be something else entirely.. But that's not important to Skye and her friends. What matters is that monthly paycheque and the swarm of aliens that have discovered the underground facilities. Can you keep them at bay while they cut down the bridges? Will you be Elysion One's Horatius at the bridge?


  • After the initial onslaught, a decision was made to take the subterranean rescue efforts, to somewhere free of the alien infestation. Scientists had recently discovered that the strange lifeforms that had been assaulting Elysion One would only venture so far into the earth. While this is good and all, there remains one small problem: someone has to keep them at bay while the operation is moved deeper into the earth. Guess who will be part of the lucky battalion?


  • Elysion One was not the first city on this planet. Built on the bones of the original settlement, Elysion One was a soaring white and turquoise edifice constructed in defiance of the elements. As you might have noted, 'was' is the operative word here. Besieged by aliens, some of the residents have taken to a ship moored in the distant quarters of the Slums. Unfortunately, it seems that the enemies have followed. Can you keep them at bay while the civilians evacuate?

Not big pack but great replayability.

Not big pack but great replayability. Four more maps mean another great time. In my opinion these maps are more easy than these included in main game but are still worth buying. In Sanctum case, there don't need to be many maps. It's Tower Defense game. You can play on many difficult levels and also on this unlimited waves (or whatever it's called) where you will spend many hours. Not sure if I can recommend it to new players, but if you really enjoyed Sanctum and want more - get it. You won't regret it. What can go wrong with simple map pack? It's good.


A good map pack for a good game.

This map pack contains one of my favorite maps. There isn't much to say about this DLC: If you want more Sanctum, get it! I loved it and on cavern I've bitten my teeth off. The maps aren't just more of the same, because they encourage new tactics and have interesting layouts. I promise you: you won't feel cheated by getting this. I would recommend to get the other map pack also since the price is fair and it is a developer who listens to their customers.


A nice map pack

The map pack contains the first DLC maps to Sanctum, if own any of it from the pack you got all for free when Sanctum is upgraded last year. If not you can buy them. Aftershock and Aftermath are open world maps, great view and detailed buildings around the core. Cavern and Slums are the opposite, both underground cave maps. The good thing in the map packs, if your friend own it you can join, you just can't play with them on campaign or host the co-op match.


It costs too much

panz3r88 | Nov. 9, 2012 | See all panz3r88's reviews »

If you like Sanctum and you want to try new challenges and maps, this pack with 4 new locations is a good choice. The maps are good and I found them harder then the one of the base game. The main defect of this pack is that it costs too much for what it offers: you must also consider that some of this maps are not completely new, but they are modifications of the maps contained in the original game


Nice pack, but a little overpriced

TheRealMoremir | Nov. 3, 2012 | See all TheRealMoremir's reviews »

Sanctum is a great game. And like every tower defense game, a lot of it's dificulty and playability comes from different maps. This Map Pack is a good addition to the game if you liked it and are looking for a new challenge. A liitle overpriced, seeing that for the same price you can buy whole games, but you can wait for an offer or use one of GMG always usefull vouchers. My personal favourite: Aftershock.
