Honestly, this game is fantastic and was an amazing game from the moment I opened the game the very first time. The soundtrack is also glorious, especially my favourite song, Diskettamine, and really lends the game a beautiful and atmospheric tone while also conveying the urgency of the situation, even before the panic effects of the songs kick in.

I think this game deserves more recognition than it's gotten, as it is just as complete and unique as any tower-defence game I've played thus far. So, honestly, yes...I would recommend this game hundreds of times over. It's easily a 10/10 if you take a little time to learn the game on the easier difficulties before finally opening up a two-plane server on Frumious.

Ugh. I loooove tower defense games but this one is dreadful. After the lengthy and tedious tutorial my first game was so annoying I didn't even bother to finish. Those are minutes of my life I will never get back.

System Protocol One is a very themed tower defense. Not only that but it does a good job creating both the tower defense and the central theme without sacraficing one for the other. The gameplay is what you would expect from a block based tower defense. You have your standard array of rock-paper-scissor enemies and towers and for the most part there is no one correct way to win. Mind you, the game can be a tad unforgiving on higher levels almost requiring you to do the "correct" build to win. And as always, there will be those who choose to juggle. I find juggling to be a cheap exploit, and if the game relys on you doing it to win then the game is fundamentally flawed in terms of balance. But overall System Protocl One is worth the price. It may be a bit too unforgiving for some, but it is still enjoyable.

tower defense with a sweet chiptune techno soundtrack that will haunt your dreams. the gameplay balance and graphics hit just the right tone of seemingly simplistic and yet richly rewarding.
