I've been playing Left 4 Dead 2 a lot recently, and quite enjoying it. Several months ago, Valve introduced a new game-mode called Mutation, a weekly-variegating modification of standard game types. There have been fourteen mutations thus far, an impressive count. And each offers a new perspective on the norm. Valve's mutations not only experiment with permutations of their game modes, but also revise and restate the emotional affect of a mode's gameplay by increasing the sense of impact, necessity, and intensity.
Two modes I've been exploring much of lately are Follow the Liter and Healthpackalypse.
Follow the Liter
Follow the Liter is a mutation of far-and-away my favorite game mode, Scavenge. In Scavenge, two teams of players either collecting as many of sixteen available gas cans as possible or, as special infected, preventing the collections. Follow the Liter more strictly narrows the objective by allowing only a certain patch of cans to be collected at a time. A new patch spawns for collection as soon as the current has been dumped.
In Scavenge, the survivor-team has the upper hand. Survivors are equipped to fell infected easily, especially experienced players who know what to expect. The challenge for infected is coordinating timely assaults that can incapacitate the survivor team.
The trouble is, with cans spread widely throughout a level, infected players often have difficulty predicting where the survivors will aim for next, excepting that they're eventually guaranteed to fuel the generator. Therefore, infected players must constantly communicate to be one step ahead of the survivors and pull off a successful gank, a task only experienced teams can negotiate. To be fair, survivors must also communicate direction frequently lest one of their team wander off in the wrong direction.
Follow the Liter is an excellent riff on Scavenge and, in my opinion, a superior game mode. Follow the Liter punctuates the core emotional qualities of Scavenge, more strictly defining the gameplay experience. Because infected have guaranteed knowledge of where the survivors will go, they can better prepare for the advance and coordinate a joint strike.
The middleman of maintaining rank becomes much easier to manage and more minute planning takes precedent. Survivors are funneled into a choke-point during each run for cans, and infected can focus on simply timing their spawns and locating specific spawn locations for optimal attacks, rather than foolishly chasing down survivors in frustration or spawning into a shotgun from feeling rushed.
Follow the Liter, as opposed to Scavenge, allows the infected team to feel more powerful, in control, and dominating…boons of the horror trade and the source of enjoyment as infected characters. The mutation accentuates what is already so good about Scavenge by more strictly tightening the rules. The mode creates pressure. And every impact as a result is energized and charged with greater force.
As survivors, Follow the Liter at the very least encourages unified formation rather than allowing players to assume their own pairs and venture on improvised paths. On one hand, this structure of sequenced singular goals incites teamwork and cohesion, especially since players know to expect more effective attacks, and where.
On the other hand, allowing only one present objective arguably stunts creativity, barring surprising and diversified approaches to can retrieval. In fact, I would say this is Follow the Liter's comparatively greatest fault, negating the myriad of styles of can collection offered to survivors, for two reasons.
First, standard Scavenge is creatively liberal, offering multiple approaches for survivors. Part of the fun of scavenge is discussing with your team members and attempting the most efficient or surprising strategy to collecting cans.
Second, the level and objective design of standard scavenge is nearly begging survivors to split up and open themselves to vulnerability. Much like the cave of wonders scene in Disney's Aladdin when Abu can't help touching the ruby despite both his own and Aladdin’s best interests, Survivors often have trouble working as a unit. Scavenge is invitation for schism between survivors, an invitation readily gobbled up by keen infected. Staying focused and communicative is the mark of a good Scavenge team, something Follow the Liter arguably somewhat negates.
The last things I would like to mention about Follow the Liter is that rounds are shorter than Scavenge, a good thing, and that rounds are potentially more balanced because each team is required to run the same gauntlet as the opposition. Furthermore, mistakes are more harshly punished. A failed gank on any single patch of cans means two to three guaranteed points for the survivors and an additional forty to sixty seconds on the clock.
Likewise, destroying cans, either as spitter or by tricking survivors into shooting them, bears greatly increased consequences, as survivors are unable to switch tacts for new cans, but must wait in agony for the destroyed to respawn, time ticking away all the while.
I never played much Versus: I didn't feel as though my attempts as an infected had any impact on the survivors' progress. Versus is where the L4D elite go to play. Many players are so good at playing survivors, a less-than-perfect attack from an infected is swept easily aside. An infected team must perform flawless ganks to even remotely impact the opposing team.
Far more importantly, though, is the emotion derived from versus. As infected, a botched attack accomplishes nothing and is frustrating. One reason for this is because any damage dealt can be readily healed away with pills or a health pack.
Suppose an infected player deals forty damage to a survivor before getting killed. The player may have even downed the survivor. No worries. The survivor just pops some pills or wraps up his wounds real fast. No harm done. All that effort, if not actually wasted, feels wasted. Sure, that survivor wont be able to use his or health pack later on which may eventually cause trouble, but the present feeling of the infected is one of disappointment and failure.
In my opinion, healing in Versus is a handicap, achieving not much more than to prolong deserved victory.
However, there is one reason I appreciate the presence of healing: the intellectual gamble of timely healing. People are greedy and arrogant. Players like to wait until the last moment to heal themselves because they want to horde their pills or health for as long as they are able. Unfortunately for them, their hubris is often their downfall, falling prey to infected before they get the chance to heal-up.
Survivors acutely feel this balance of risk and reward because they do not want to use their health packs until they can receive the item's full benefits. Pills are a larger problem, in terms of game design, because they temporarily heal thirty health almost instantly, meaning they can be used at even 70% of full health and still receive the full benefit.
Healthpackalypse is mutation of Versus, removing all health items from the game. No pills, no adrenaline shots, no health packs. Only a single health bar fast on it's way to depletion. Survivors can no longer heal-up and move on; any damage they sustain stays that way.
This design has fascinating repercussions on the experience. Infected players have easier opportunity for more individual impact because even fifteen damage has an effect. It feels amazing to deal damage and relish the fact that your victims are unable to undo your efforts.
However, for the very same reason, infected team-play is less essential. Teamwork and cooperation is still extremely effective, fun, and recommended, but the mutation lessens it's necessity.
Healthpackalypse for survivors, meanwhile, is a more tense, frightening, and suspenseful experience. Mistakes carry larger consequences because the Ctrl+Z function has been removed. Cooperation is vital. It is the reverse of the affect upon the infected experience. Solo play is disastrous because healing is impossible. This incites unifying teamwork.
Valve's mutations are interesting revisions of their established game-types. As revisions, they offer different experiences, some positive, others negative. It's great to see a company still experimenting with a proven success, stating that maybe there is room for improvement yet. Largely, I think at least these two mutations discussed help to accentuate the emotional qualities of the modes, but dilute the intellectual qualities.
And game design aside, as a marketing strategy, mutations are genius, hypothetically rejuvenating the established player-base while inspiring new customers. Especially when paired with Valve's approach to free DLC, like The Sacrifice coming October 5th.
Mutations are refreshing a game nearly a year into it's life, a long time for most video games.
