I have played many Roguelikes, and played many First Person Shooters, but I have not played many First Person Roguelike Shooters. It is a small collection of games to be sure, but it is seeing increased popularity in recent years, in part due to the game Paranautical Activity, among others; others, such as this, Tower of Guns. Although it is apparent that there is still a ways to go before we can get the true, full blooded FPS experience from procedurally generated games, what Tower of Guns is showing is that we really aren't that far off.
I truly believe in the potential of this game, and what is already here is beyond great; it sets a benchmark for what can be done in the future, it's future, as well as the future of others. The guns are all unique and the movement, while a bit weird when interacting with certain situations, works. The verticality of ascenscion from one room to the next is believable, and feels like it fits within the confines of whatever mammoth you happen to be scaling, and it helps that the room designs are intriguing, and full of secrets. If there is another thing to be said that needs to be said, it's that you have played this game before. Well, not this game, but you can identify certain elements of other games that this game is brimming with. It's quite a Quake of them, actually, and this isn't a typically good thing; in this case though, it is very much a good thing.
You will feel right at home with the controls if you are a veteran of the old school of FPS, and will certainly appreciate the need for movement in order to survive; staying in one place while Knee Deep in the Combat of ToG will be your DOOM. It is certainly Unreal the level of chaos that you will encounter in most situations, but you know what, it's a good thing; and in fact, this game is a good thing. So good, that while I could write on about the personality that this game has, from the music to the art and dialouge, I feel only the need to say one more thing: Tower of Guns is a milestone in game development; and it was all thanks to mainly one man, Joe Mirabello. So here is my reccomendation, and my sincere wish: Joe, continue making games; and to everyone else, please, buy this game. I highly recommend it :)
