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 !
OK. The 4 is for the mapping effort. The maps look good and the overall presentation is fantastic.
...but....
...what the hell were you thinking with the Antlions. This isn't fun. A constant stream of Antlions trying to kill you at all times is just plain annoying. They're always in the way. You never get a moment to look around or understand what you're supposed to be doing. I just ran around chaotically trying to find somewhere to go and never made it out of the first map.
Have Antlions come in waves or something but for goodness sake please allow the player a moment to breath...
