This project began a few years ago more like a self-challenge: while I was playing Wolfenstein 2, in the prison area where you have to avoid a ceiling mounted turret, I had the idea to see if I can program such a turret, in Unity. I downloaded from the store a free turret models pack, some particles, skies etc. and began programming and tinkering. After making about 5 turret types, I asked a friend, who knows a bit of 3D modelling, to make me something to defend (a base) and some attackers (robots). I also wanted to give it a bit of twist, to engage the player more in the action: I put him inside a tank (which I also got from the store) to help defend its base against large number of invaders.
Unfortunately, due to the lack of time and manpower (mainly artists), the project remained in a proof of concept state. The scripts are also full of obsolete APIs, being written back when Unity 4 roamed the earth. I plan on rewriting it entirely and hopefully bring it to a playable / sell-able state in the medium to distant future.
