Cobos

Just watch the video to understand what the game is like. If you have already watched then there are some tips:

It's a 3rd person arena shooter; Enemies spawn in special order and you have to find out it to win; Every enemy has a special behavior, weapon and task; Where you run is more important than who you are going to kill; It's ok if you die 10-20 times before win the first battle. Don't forget to use a second weapon.
