A while ago, I came up with a scoring system for Infection that is fair to both sides. I’ve finally decided to post it here on Waypoint, to open it up to a wider audience.
The system is called “Time/Victim-Time Scoring”, or “T/VT Scoring” for short. I apologize for the length of this post: the system is simple, but the goals it accomplishes are many and varied.
THE STATUS QUO
In any given game of Infection, Zombies have infinite lives, Humans have one life and finite numbers, and scoring is based on kills. This means that the Humans have a maximum total score limited only by their ammunition. For all practical purposes, Humans have an infinite maximum total score, while Zombies have a maximum total score equal to the number of Humans. In other words, the current scoring system favors the Humans.
ELEMENTS OF AN IDEAL SCORING SYSTEM
These are a set of principles, existing elements, and assumptions that describe the goals of an ideal Infection scoring system. They are referred to throughout this post.
BASIC PRINCIPLES- Players should not automatically have higher potential scores than others solely as a result of random team assignment.
- Players should be rewarded for completing the respective objectives for their sides.
- The Humans’ objective is to survive for as long as possible.
- The Zombies’ objective is to kill the Humans as fast as possible.
- As the round progresses, it should become progressively more difficult for an individual player to complete their team’s objective.
EXISTING ELEMENTS THAT WE WANT TO KEEP
These are principles that are observed in existing Infection gameplay, and that should be maintained.
- For Humans, the increased number of enemies makes it more difficult to survive late-game. This satisfies Principle #4 for Humans.
- The Zombie objective becomes easier for the whole team late-game due to their increased numbers, but it becomes harder for each individual. That is, the chances that any one particular Zombie will be the one to complete that objective will decrease. This satisfies Principle #4 for Zombies.
ASSUMPTIONS ABOUT GAMEPLAY- On a balanced map, longer-lived Humans are more skilled or otherwise better-able to survive. Ergo it takes more skill/proficiency to kill them.
- When a Survivor Victory occurs, it means that the Humans have won. The scoring should reflect this.
MY SYSTEM: TIME/VICTIM-TIME (T/VT) POINTS- A player’s score in the game is the sum of their human points and zombie points
- A player receives one human point for every second in which they are a Human and are alive
- Upon killing a Human, a Zombie receives a number of zombie points equal to the number of human points that the victim had for the current round
AN EXAMPLE
That’s not the most intuitive explanation, so here’s an example: a description of how a single round with four players might play out, using this system for scoring.
Arthur, Beth, and Chris start the round as Humans, while David is an Alpha Zombie.
Twenty seconds after the round begins, Arthur, Beth, and Chris will all have twenty points for this round (that’s how long they’ve been alive).
At that precise moment, David infects Arthur. Because Arthur has been alive for twenty seconds, David receives twenty points for his kill. The score is:
ELAPSED ROUND TIME - 20 seconds
ARTHUR - 20 (20H 0Z)
BETH - 20 (20H 0Z)
CHRIS - 20 (20H 0Z)
DAVID - 20 (0H 20Z)
TOTAL HUMAN SCORE - 60
TOTAL ZOMBIE SCORE - 20
Thirty seconds later, Arthur infects Beth. By this time, Beth has been alive for 50 seconds, so she has 50 points, and Arthur gains 50 points for infecting her.
ELAPSED ROUND TIME - 50 seconds
ARTHUR - 70 (20H 50Z)
BETH - 50 (50H 0Z)
CHRIS - 50 (50H 0Z)
DAVID - 20 (0H 20Z)
TOTAL HUMAN SCORE - 120
TOTAL ZOMBIE SCORE - 70
A full minute later, David infects Chris. By this time, Chris has been alive for 110 seconds, so he has 110 points, and David gains 110 points for killing him. Because Chris was the Last Man Standing, the round is now over.
ELAPSED ROUND TIME - 110 seconds
ARTHUR - 70 (20H 50Z)
BETH - 50 (50H 0Z)
CHRIS - 110 (110H 0Z)
DAVID - 130 (0H 130Z)
TOTAL HUMAN SCORE - 180
TOTAL ZOMBIE SCORE - 180
Notice that the total scores for the two teams are equal, despite players switching from the Human team to the Zombie team throughout the game. If we assume that all players are eventually infected, then for every point that a Human gains, the Zombies will eventually gain a point of their own (upon killing those Humans).
