“Defense Grid 2 feels paradoxically foreign and familiar...Ostensibly, the meat of Defense Grid 2 is the campaign and the narrative arc it carries.”
8 – Eurogamer

“9.5, Exquisite”
9.5 – Gaming Nexus

“Super Addictive!”

Special Edition

Special Edition purchasers will receive the digital book, The Art of Defense Grid 2, plus the ebook, The Making of Defense Grid 2: The Complete Story Behind the Game by Russ Pitts, and "A Matter of Endurance" audiobook written by Hugo award-winning author Mary Robinette Kowal and performed by the English cast.

THE ART OF DEFENSE GRID 2 digital art book celebrates the talents and efforts of the people responsible for creating the visuals of the game. It is an insight of the concepts and variable directions that the team explored during the game's creation. The journey in visual exploration is a winding and strange path at times. This book revisits that journey, come along and enjoy it.

THE MAKING OF DEFENSE GRID 2 brings you behind-the-scenes of the creation of a modern video game.
Over nearly two years and hundreds of hours of interviews, veteran video game journalist Russ Pitts (Polygon, The Escapist) has been given total access to every stage of development, and dives deep into the technological innovation, creative artistry and hard-nosed business that combine over weeks, months and years to make a game.
From moments of startling inspiration to times of crushing stress, the author has been present for every aspect of production — major milestones, critical beta tests and sometimes contentious design meetings.

THE MAKING OF DEFENSE GRID 2 is based on the article series written by Pitts for Polygon, with expanded interviews and never-before-seen material. The result is a look unlike any other into the hidden world of game development and the high stakes gamble of making games.

A MATTER OF ENDURANCE: Written by two-time Hugo award winning author Mary Robinette Kowal and performed by the English cast, A Matter of Endurance is an audio play staring the characters from Defense Grid: Containment (AI General Fletcher, AI General Cai, and Commander Simon Ritter) and introduces Maralon’s Governor Teydell as you (the Commander) and your AI companions journey from the destruction on Maralon to the destination of the Outer Colonies where the events of DG2 take place.

About This Game

Defense Grid 2, DG2, is the highly-anticipated sequel to Hidden Path Entertainment’s 2008 Defense Grid: The Awakening. Setting the bar as the definitive tower defense game, Defense Grid 2 introduces new worlds and threats to test your tower placement strategies. With a bold new look, a compelling single-player campaign, and the addition of new game modes, online player-versus-player and multiplayer co-op, every play-through brings fun new opportunities and challenges.

DG2 comes with a story campaign featuring 21 stunning maps, dynamic level movement, an expanded story and cast of characters, hundreds of challenge mode experiences, new multiplayer modes, a procedurally driven audio score and the ability for players to build their own levels. DG2 also introduces players to DG Architect on the PC, a level creation tool set connected to Steam Workshop where players can create their own unique levels to share and possibly even sell if selected.

DG2 for the PC was funded in part by Dracogen, a private investor after a 2012 Kickstarter campaign funded the original game's DLC, Defense Grid: Containment. DG2 is developed by Hidden Path Entertainment and published by 505 Games.

Thoroughly disappointing tower defense game. Buy DG1 instead - it's a much better game.

This new version has a stupid story, a variety of useless support weapons (the resource one is always going to be the best) and difficulty so unsteady you'll wonder if it was ever tested. The last few levels of the campaign are a joke - you will never feel threatened, unlike in DG1. Some levels in the middle of the campaign are difficult but otherwise the game is a cakewalk that presents little challenge (again, compared to DG1), even if you are trying to "max out" every level. Also, there is workshop support but the place is barren. Clearly, this game never took off as I had hoped it would. So sad to see such an inferior sequel :(

much like DG1, a simple but solid TD with good graphics, nothing special.

negative vote for the abuse of the steam workshop for selling maps and having no support for free community maps built into the game interface. selling maps is ok, but controlling competition in favour of your own content simply sucks big time.

If you like a good classic Tower Defence game, then this it is.

Has the same gameplay but also has the flexibility of co-op or versus when playing with a friend.

Truly engaging so far and can be quite challenging as you work through the different levels and options.

Where to start with Defense Grid 2 except "OMG"?

This game is so intense and filled with so much new mechanics I had to replay entirely the first Defense Grid just to measure the improvement (true story).

~ Spoiler alert : a few tips and tricks are listed at the end of the evaluation

The first Defense Grid featured specialized towers and one deadly strike from the heavens. The second opus features almost the same towers, with a twist: you now can build them on top of Boost towers, and activate a special effect on them: Disrupt shields, Overcharge towers or Boost score - your choice.

On top of that, you'll meet new AI on each mission, and pick one of them to support your efforts. Each AI provides you with an advantage that can be triggered and requires some time to be ready again: the classical strike from above, more resources to spend, overcharging a group of towers... - your choice again.

And if you think that would be enough, think again. Not only the towers can be upgraded from level 1 (green) to level 3 (red); but you now can tweak each of them with nice improvements like: revealing hidden enemies, damaging over time, focusing on the biggest enemy ... - your choice !

To keep the pressure on, the clock of each mission starts without waiting for you to analyse the layout. So you'll have to think fast and fail a lot before you nail the level and reach higher scores. Luckily, you can go back to the previous checkpoint and readjust your strategy (there are more checkpoints so you don't feel like being forced to restart entirely a level).

~ And now some tips and tricks (don't read them until you hit a wall of difficulty)

First, the levels can have the same entry / exit point; or a different entry and exit points. Some maps have multiple entries and exit points and can be tricky!

Second, the levels can be roads surrounded by tower locations, or made of large chunks for concrete where you'll have to build a path to channel the aliens.

Even if it is possible to fill a level with level 1 towers and still win, ultimately, you'll want to concentrate devastation on carefully selected spots where the aliens will walk multiple times.

So, what are the best / worst towers in the game ? On my own, I mostly play using Concussion, Temporal, Laser, Machinegun and Cannon. Sometimes Missile. The Concussion is so powerful you'll eventually forget the Inferno, the Tesla and the Meteor. It's a shame but you're not here to concede anything.

Next questions are: where should you place the towers, how should you combine them, and what are the best boost to give them. Here are my suggestions.

First, in each level, locate the entry & exit points. Then assess if you can change the path of not. If you cannot change the path, locate where you have bottlenecks and paths that can be targeted twice (or more) with a single tower. Usually, the Core Center is one of them.

Once you've located or created these bottlenecks, decide where are the best spots to concentrate damage. Sometimes it's at the very beginning of the level, sometimes close to the Core Center, sometimes somewhere else.

- Build a Concussion (on a boost if you can channel the aliens, or benefit from back-and-forth; and on land if you cannot change the path) then at least a second one close to the first so you can combine the effects). A good boost is Overcharge or Score Boost if you aim for the top of the Ladder :)
- Right after the Concussion, build a Laser that will continue to burn the aliens. A good boost is Overcharge - unless these are far from the Temporal so Disrupt is a better choice (laser don't go through shields)
- Build a Temporal close to the Concussion towers to slow down the fastest aliens and nicely melt the other ones. A good boost is Disrupt, to remove those nasty shields. (And when I say " melt" I literally mean "melt").
- Build Machinegun(s) near the "entry" of your Concussion / Temporal / Laser combination. A good boost is Overcharge unless there aren't close to a Temporal with Disrupt ; then Disrupt is a better choice.
- Build Cannon(s) to cover either or both the entry and exit of your Concussion / Temporal / Laser combination. A good boost is Overcharge.
- Make sure Cannon(s) or Machinegun(s) are protecting the Core Center. A temporal can help too.
- Build Missile(s) to cover the Core Center, Kill zones and especially exits - you don't want one remaining alien on the brink of death getting away with your precious cores :) No sir, you don't!

About the "tweaks" in the towers, here you enter the realm of preferences. Usually I use "Focus on biggest target" on Machinegun, Cannon, Laser and Missile since the Concussion will usually get rid of the tiny swarms. On Temporal I try to boost the slowing down effect. On the Concussion I try to raise the damage.

But once you're acquainted will the levels, feel free to experiment! You may choose to tweak you towers to slows down the aliens as much as possible, or to damage them overtime, or pierce their shields. (Now this game sounds like your regular ARPG, doesn'it it?)

Have fun!
