The year is 2457. Humanity lives on dozens of worlds, and almost everything is controlled by the state. I say "almost" because a few colonies broke away. One such colony is Sola, an inhospitable ice-ball of 800,000 inhabitants. The government send an army to obliterate Sola. Within in two days, the population has been reduced to less than 2,000 and what little of it remains hides in shadow, praying for a miracle. However, it is quickly becoming clear that the invaders aren't the most dangerous thing on the planet, and that the new threat might also be Sola's salvation...
I can't decide whether or not to tell part of the story from the perspective of an enemy. He could be:
Part of the officer cadre, highly educated, and under pressure to eliminate last vestiges of local resistance. They have three months to confirm the deaths of the last locals, or they will face a firing squad.
Part of the criminal company, so he'd be one of many convicts. Between them, they have committed every crime under the sun, and now they have guns and have been set loose on the locals. Characters witness them torture and then execute captured civilians. Almost all of them choose to flood their systems with steroids and combat drugs, which make them even more psychotic and merciless.
Ordinary soldier. Very indoctrinated, basic education only, most are conscripts. They make up bulk of the invasion/occupation force.
Do you think I should include this kind thing? It might help make the enemy seem less two-dimensional, but it's already seen through the eyes of both the protagonist and, on occasion the deuteragonist, and I heard a lot of people find POV switching annoying.
You seem to be confusing this too much with the idea of writing for a game. Having written, and read, plenty of stories (and read a lot of novels), and worked on game writing, I can tell you that the POV switch is a common and very useful tool in writing longer works like books - it's only a problem when you use it in game writing. Very few games do this effectively, some exceptions being the game Dreamfall, for example, which uses it well. But in your novel, I'd say that having multiple points of view is a good thing, especially if those points of view conflict. For example, I'd direct you to the works of Ian Irvine, an Australian author. In his fantasy epic, the Three Worlds Cycle, there are often multiple factions and groups working against each other or in allegiance with each other, and he often switches from the point of view between chapters of one group to another, usually one with conflicting goals. In the first set of books, for example, he switches from the main group straight to their main enemy, and vice versa, plenty of times, to show the differing thoughts, motives, ideas, goals, and so on, that each group has.
Therefore, I'd suggest you do include other main characters,
IF IT WORKS WITHIN THE STORY CONTEXT. That is very important, that bit in bold caps. If you can reasonably work several characters into the story who are part of differing factions, then that would be great, and you can reasonably switch between them. As both a writer and an avid reader, I tend to prefer that myself because following one or two characters for the entire book gets boring (unless it's the main point, like a first person perspective work). Multiple views gives a much more interesting take, and allows you to build up conflict and build up differing views for the reader to think about without having to come up with contrived situations to do so. Particularly moralistic viewpoints.
At the end of the day, these are just my two pennies (or more), and it's up to you. But hopefully this helps you make a decision you're happy with, and that will give your future readers something much better to read. Either way, good luck with the book, and if it gets published let me know what it's called and where it's sold and I'll give it a look
