You have been sent alone, to a warm desert planet for a commando mission of high risk. Your goal, as an elite soldier, is to infiltrate the abandoned human complex to perform vital maintenance tasks and to recover precious scientific research facility data. From the warm desert to the depths of the complex, you will blow up everything that blocks your way, like doors or walls, but mostly aliens. You will then be extracted from the planet by a space ship !
Fun for a bit. The use of Antlions is confusing; it is unclear at first that the game is not set in the Half-life universe, so when I saw antlions, I automatically assumed "Stay off the sand!" but found out this was not the case. Would probably be better to make changes to the antlion enemy models if the mod is going to use a different setting.
Framerate dips more than it should, I put on mat_wireframe and it looked like there was way more rendering than there should be. Could be better use of visleaf optimization.
Apart from those issues, it is fun to play, and there are some creative sequences.
