|My "control panel" for Xenomorph: health, skills and turn counter.|
I started fighting a small xenomorph on my second game. It was easily killed. Then I found a shield that improved my defense. Then I found an alien scout and died again.
On the third game, I found a shield right away, then met a brute alien -- game over.
This is a very simple game, with very low odds for the player. Still, it works well to kill a few minutes. Although there are similar offerings for free, like Dice of the Living Dead, I think it is worth the price. The publisher also has a number of other mini-games at similar prices, and some free downloads.
