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.

Released in 2010, System Protocol One is a network security themed tower defense game. The graphics are what you would expect from a game with this theme. This day and age, there is a proverbial flood of tower defense games available. In the now tiring genre of tower defense, this game does little to set it self above the rest and while it does have a few unique aspects in my opinion it's ultimately not worth playing.

One notable issue I had with the game was pacing. The tutorial was a painful bombardment of game mechancis; unlike Defense Grid, which paces various mechanics over several levels so you can get familiar with them, this game slams you with all of them at once and throws you into game to engage in a trail and error process of figuring it all out. I have also noticed issues with the difficuty pacing where certain waves will drastically increase in difficulty.

I digress, but as a systems administrator, I felt like the developer could have done something more clever with the conept of "maintaining uptime" while "securing the network", as hinted in the tutorial. Sadly it seems the only implentation of this concept is the need to keep at least one open path.

The game does have some unique aspsects, and if you like tower defense games you might appreciate this game. However if your are more or less neutral towards these sort of games there are better options available if you are in the mood for tower defense.

Score: 5.5/10

This game wasnt bad when it was released but tower defence games have moved so far beyond this one that I just can not recomend it. Especially with great titles like Defence Grid, Defenders Quest, Fieldrunners 2, or even Prime world: Defenders. System protocol One is simply completly dated, and not in a lovable, retro, nastalgic way either. Its not a terrible game please dont misunderstand, it is just in a genre with great games that have completly raised the bar of standards and expectations beyond what this game now offers.

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.

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.
