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.
