Let's Play Serious Sam Fusion: 7Smoke Tennis 2 - Part 1 - Mr. Angry

We begin with a flashback to a time when our protagonist was just a toddler. He remembers escaping from his crib and climbing onto his mother's bed. He remembers how much she played Serious Sam and then he'd pretend to summon Mental's horde and fight them in the bedroom. This would get the attention of either the landlord or a representation of our protagonist's father nicknamed Mr. Angry. One day, Mr. Angry got so upset at us for summoning Mental's Horde that we and our protagonist's mother had to pack up everything and leave.
