Defense Grid 2 is hard. Make no mistake about it. I hit my first wall at level 8 and found an uphill climb after that. Those new to the tower defense genre will find its difficulty curve unforgiving. Yet, somehow, this challenge ends up feeling rewarding.
Defense Grid 2 is a fairly typical Tower Defense game at its core, but the layers of complexity give it a lot more staying power and replay value than you are likely accustomed to. With 21 campaign levels, and plans to offer countless more as downloads, there is no end to how much time you can spend with DG2, and that's not even counting fighting for placement on the leaderboards... or multiplayer. DG2 is a shining example of Kickstarter done right.
Defense Grid 2 is, quite obviously about defence, but it's also about being passive, about observing morally grey conflicts play out in front of you - without your input.
Defense Grid 2’s new variations on the original’s excellent tower defense gameplay pulled me right back into the compulsively addictive quest to destroy all aliens with a minimum of expenditure.
Defense Grid 2 is a solid effort in the tower defense genre. The game is packed with plenty of different towers and well designed maps, though the campaign only lasts five to six hours if you don't consider the alternate levels.
Defense Grid 2 is a good tower defense, with a simple control system and immediate mechanics which unfortunately are also the biggest limitation of the production. The game is missing the new and bold ideas that usually make the difference, and relying solely on the community may not have been a winning choice.
