Enemy spam in game design

There coming out the wall!

Enemies are a staple of a good many video games out there today, and for very good reason; they represent an active trial for the players to overcome through strife that can feel exciting and dynamic in a way that's hard to replicate with static puzzles and gradual progression. That is, of course, just a general overview of their potential role in gaming; enemies can serve many different roles for their respective games and that's what makes them such a universal aspect. That does not mean, however, that there is no etiquette or widely excepted methodology to the creation and implementation of said enemies; but I'm only interested in one specific set of rules and that's those that go into deciding the sheer quantity of enemies. What counts as just enough and what crosses into the borders of 'Enemy Spam'.

'Enemy Spam' refers to a situation in video games wherein the player meets an enemy force that vastly eclipses their ability to handle it. As such, what actually constitutes 'enemy spam' can vary wildly from game to game; it comes under the banner of balancing for the title in question. In some games, enemy spam could be considered having a group of five enemies thrown at a player in a very one-on-one style game, or having a constant barrage of enemies thrown at them again and again in a very resource heavy style game. What's important to note and make distinction of is that 'Enemy Spam' isn't used to denote a moment at which a player's ability is heavily challenged, even when it's to a degree outside of their supposed limits; but rather a time when the amount of enemies, or the type in question, are so consciously geared to be disadvantageous to the player that it starts becoming frustrating, and loses that hard-but-rewarding edge. (It's a fine line to walk.)

Personally, the first time I really came up against 'Enemy Spam' was in the party-based RPG 'Dragon Age: Origins', which I'm sure you all know so well. That was an entire game built around the core concept of intelligent use of character skills and positing in order to overcome the threats of the game. (Although, all too often that did slip into micromanaging the every move of your teammates. The AI wasn't the best on the market.) This meant that throughout the majority of the game you'd come up against smartly constructed groups of enemies that would test your versatility and strength as you devise counters against the many different enemy types, with the finale of the areas typically testing all of the strategies you had made in your journey. By the climax of the game, however, the team had run out of new enemy types to throw your way and thus just resorted to placing armies of Darkspawn in your path. This was still completely fine and dandy right up until the final hallway of enemies before the final boss; because there we all saw the quintessential example of enemy spam.

There, in front of the player, were a layout of battlements manned by Darkspawn; surely a challenge for any player to get through and requiring of some tactical planning. Bioware, however, saw to it that people wouldn't have a chance to get to planning as the second you get there you'll be hit by a wave of invisible Shrieks to throw you off your game. Good play, Bioware, but now it's time to get back to- oh, there's another wave. And another. And another. Now this isn't any where near the worst example of enemy spam, but in a game that, up until this point, had relied on strong enemy composition rather than overwhelming numbers, it was supremely jarring. And all that was compounded by the final fight itself, which swarms unending waves of enemies at you requiring anyone on higher difficulties to literally bring an entire apothecaries worth of potions just to withstand the impending hoards. (Not really the sign of a well-crafted boss fight.)

Now this is by no means the only example of this sort of issue popping up in the game balancing, and in fact; Bioware themselves are responsible for an inordinate amount of it. There's the corridor of endless Sith at the end of KOTR, the Geth Juggernaut hallway up the Citadel tower in Mass Effect and probably something at the end of Jade Empire that I haven't got to yet. But there are other examples from different game franchises. Some might say that the later Dark Souls games resorted to increased amount of enemy spam to fill their areas (although the Frigid Outskirts from Dark Souls 2 is easily the worst offender in that regard.) The final level of 2016's DOOM is split in three nauseatingly prolonged combat arenas, all enough to make you never want to see another Demon for as long as you live. The newer XCOM games have spammy final levels, as does The Outer Worlds and certainly some of the Kingdom Hearts games.

But where is that line in the sand? At what point is more enemies too much and how does a developer know how to effectively walk that line? You may have noticed a trend out of the games that I mentioned, in that most of the egregious offenders pull their spam by the final levels, and that makes sense when you think about it. The finale of the game is supposed to represent the climax in spectacle, story and gameplay; so it makes sense for the developers to throw everything they can at you. But when they just inundate you with so many enemies that the game devolves into a substandard version of itself, suddenly that's too much and considered 'Enemy Spam'. It's a very tight line to walk and I envy no one who has to do so for a living.

Perhaps the hardest task of game balancing is figuring out the utmost extremes that your game and, most importantly, what your players are comfortable with; because realistically there is no right answer. There's no cure-all, one-fits-all, choice for how to attain perfect equilibrium and  therefore Devs just have to work off what little they can judge from their play testers and a little bit of instinct. Some games can totally get away with chucking the kitchen sink at you without ruining anyone's day; just look at the finale of 'Batman: Arkham Asylum' for instance. Just before the final encounter the player is asked to walk through a room brimming with clapping thugs on either side. Now this is entirely optional fight, and the key may lie in that, but I feel it's just the makeup of the game's legendarily tight combat controls that the action of knocking out everyone in that room still feels satisfying by the final punch. So as I say; different strokes for different folks.

Of course, personally I wouldn't say that Enemy Spam essentially ruins a game, but it does leave a sour taste in the mouth for the player which is rarely relived by the eventual completion of the task in question. For my two cents, I feel it's just a little unfair to be thrust into an overwhelmingly packed situation without being made aware of it prior. Perhaps it's the surprise of "Are we done ye- another wave?!" which really stings the worst, or perhaps I'm being reductionist with even that and there's an even wider net that could be cast here. Either way, I would be interested to hear a perspective for how enemy spam is handled from both a developer and player level, but as this was just an introduction to the topic, those are a couple blogs for another day.
