This game BARELY cuts the mark for that yes, and it's for the reason everyone assumes: the port is clearly an afterthought and I was never allowed to forget that while playing. For example, I eventually started pausing mid level every time I wanted to upgrade a tower, because actually selecting one with the mouse is a hit and miss thing - it tries to grab and slide the screen instead, which is utterly useless since the whole map fits fine in my screen. And don't start me on the level selection slider. The appropriate asking price tipped the scale towards yes for me.

That huge aside aside, this is a solid tower defense game of the more traditional variety, with fixed paths and some interesting mechanics - just don't expect a reinvention of the wheel. The maps of the campaigns repeat once too often for my liking, however they're intersting enough and at times challenging. I like the difficulty, though the curve can occasionally be steep and some grinding seems to be encouraged. It is mildly addictive, the graphics are fine and scale alright, the music is okay but can get very repetitive. All in all, as TDs go this one is lukewarm: decent, not great, not bad.

Pet peeve: It's really sparse on information about the levels, the enemies, the towers and the upgrades. I especially miss details on the enemy types (an icon and a level are not info enough in my book). More practical details at the level selection page would also help plan what towers/weapons to pack along. However, since many of the maps are pretty solidly geared towards one or two winning strategies, you could consider that part of the design: this is less a plan ahead and stratgize sort of TD and more a "jump right in and take the hits as they come" one. Personally, I consider the lack of information just another sign of a game made for smaller screens and less reading.

So buy? Yes, I suppose, if you're a TD fan and running dry. Especially if it's discounted and practically free. There are many MANY great TD games for PCs out there and this isn't one of them, but it gave me enough hours of fun to pay for itself.

About what you would expect from a 5 dollar game... except that its a couple bucks more than that.

Its a TD game, but not a very good one. The levels are all very bland and "samey," there are very few enemy types (although they can vary in strength amongst their kind), and it is very easy. The game never introduces anything which forces you to change your play style; your first two towers are all that you need to beat most every level.

The game tries to add some spice to the typical TD recipe by including a commander unit who can move from one key point to another and engage the enemies directly, except that it isnt very well implemented. There is no penalty if he dies, and he doesnt really do much for a very long ways into the game. The key locations that he can guard are basically capable of handling themselves without his help, as long as you add one bomb turret and a couple of lasers.

The game feels short, even though it takes awhile to beat. There are only a small number of maps available, so the game repeats several of them with "different" waves of enemies (which dont feel different at all due to the limited variety) and tries to extend gameplay by making you face absurdly high wave counts (50+ for most levels).

I like TD games, and i have played a ton of them... but this game felt half ♥♥♥♥♥ and amateur. There are plenty of good TD's out there; this one isnt worth your time.

I hate myself for trying to play this game, it starts out good (first hour) but then it's the same over and over again. The more difficult it gets the longer it takes to clear the stages (it actually doesnt raise the difficulty) so its always easy. It just takes forever, It's will slowly drain the life out of your soul,

2 campains / 40lvls of the same stuff, 4 difficulty settings = 160, + endless and challenge mode = i dont know 40 more / 200 levels

A level usually takes 20min on easy and up to and hour on hardest, on endless mode its infinite so if you want to beat the game, its atleast 200hours. And it's the same thing over and over again, you dont need to think or do, just sit there and watch for 200hours, sounds like fun right? well it's not!

I don't agree with some of the harsher reviews on this game. This is a pretty good TD game. I own it both for the PC and Steam and I enjoy them both. The graphics are just fine and look good on my 1440p monitor. I do have a few complaints about the interface, though. To me, the space bar should pause the game, but it does not. Escape should open a menu, but it closes the game with no warning. This game also runs really hot on my video card. The fan on my GPU maxes out when this thing is running, so there must be some real inefficient code running behind the scenes. The game still works just fine, though. I would recommend this to anyone who likes TD. You can see samples of this playing in HD on youtube.

First things first:


I am sorry, but it is. This is exactly the mobile game, ported to PC without changing anything. It has no resolution options (and only a low/high quality setting, nothing else). It only runs in window mode or in a stretched (!) fullscreen mode. Really, really bad. I have a native resolution of 1920*1200, so why the hell can't I get this exact resolution in the game? Instead I get this ugly, stretched mess. But ok, I can live with it. Tower defense games were never about the graphics, right? The interface is exaxtly what I know from the iphone. They really didn't change a thing. For instance, if you drag a weapon to a free slot in the armory, it becomes zoomed in in your hand/mouse cursor, which makes sense on a mobile device. It looks horrible and ridiculous on a full HD display though. And they added absolutely nothing. No achievments, no trading cards, no nothing. I really have to assume, that the developers only wanted to make a quick buck with this.

Which is really a shame, because the game itself is actually great. It is exactly what i expect from a tower defense game. Looking at all the newer TD games which try to implement more interaction (like running around with a hero), this is rather old-school. And it is exactly how i like my TD games. Searech for optimal spots for your towers. Find the right balance between getting lots of interest each round and not dying. Love it! And the commander is a nice addition to the already great gameplay of its predecessors. It gives you a little bit of additional interaction, but not too much. For me personally the commander is about as much interaction (besides placing and upgrading towers) as I can take. Perfect!

I really like this game, and that's why it gets a thumbs up. I was really struggling though, because this port is basically a punch in the face of all Sentinel fans. I would have expected more. I pay more money for this than on the iphone after all, so I think i can expect more, right? Whatever, the game is still a lot of fun. If you like traditional tower defense games, this might be the game for you.
