So, the elves are true, the reindeer is true, and the way Santa gets money is by killing demons is true. Man, I thought the story about him getting presents from Walmart was unbelievable.
I think the best strategy is this, get lasers for core to get sidekick and awesome laser, get magic for one are to take out glass and use darts for other arm in case you're weapons are still reloading.
First mission: take out guy near door. Second mission: take out bodyguard on far right, then take out guy at desk. Third mission: take out guy once he is able to be hit. Fourth mission: shoot guy on train reading newspaper on far right. Fifth mission: shoot top guard, then right guard, then bottom guard, then left guard. Do this very quickly. Sixth mission: shoot target as he is walking up the stairs. Seventh mission: when the two guys meet take out one on right, then hit the second one before he runs away.
that was a horrible bug that i plan to make as a skill in the sequel haha.
