The Guardian Legend Legacy stream recently played by some russian guy. If you did not know about that project then you can see what it is. I am not sure if they keep doing it because I am away from russian social network VKontakte.
In that game you can choose your primary weapon and your subweapon. The walking stages are randomly generated. So each time you start a new game it will have different map.
If you want to annoy author and tell him to continue the work then here is his youtube channel.
And here is this project page on facebook. You can find the download link there.
Or you can reach him on our forum!
