With a bit more content and a consistent playerbase this could easily become my main game. The controls are intuitive and although the enemy AI is not very strong even on elite and could use some work, I have definitely had difficulty doing solo sieges. As for performance, the game runs about as smooth as anything on my computer can, but I'm not sure if that's because of the developer of this game or the developers of s&box. They have separate volume controls for music and sound effects, which is very useful if you want to listen to your own music without muting the game entirely. One small problem I have with the game is that you can't pause, even in singleplayer. If you press escape, it automatically forfeits. Apart from that and the lack of content, this is a good game and you should play it if you have the time.
