Intruder's Thunder 3: Shadow Destiny is the sequel to Intruder's Thunder 2. It has an all-new rendering engine utilizing LWJGL, a new soundtrack, and various other improvements over the last game. As of 11/23/2013, there is a demo version available. I still need to develop more content for the game, but the first two levels are basically done. Please give it a try, and let me know what you like/do not like about the game. Any feedback is welcome and appreciated. Currently, there are Windows, Linux, and Mac versions. I have not tested out the Mac version, but it should work.

Glad you enjoyed it! Adding C4 and disabling the blood animation when you hit allies would be fairly easy to implement. Swim animations would take me a long time, though. What did you think of the level design; too easy, too hard, or just right?

Wow, this game is pretty immersive!
My only complaint is the graphics look a bit small, but other than that, fantastic job! Keep up the good work!
