Just what the title suggests, I’m getting the impression this might be a new beast entirely. I don’t doubt that it’s a first person shooter, I don’t doubt that therell be vehicles or multiplayer, but on the Campaign perspective, the enemies are almost guranteed to be different and that puts the “fun” in jeopardy. The fun in Halo Reach through 3 (Chronologically speaking, which includes 1 and 2) depedned on how the enemies played and how you could kill them, and what was great for the story was that their behavior went along with how they were portrayed in the story.
The Sangheili are not soldiers and they never fight this way. They are warriors, independent from one another unless in specified unit like the Spec Ops. Other than that they’re WARRIORS and therefore have an excuse for running out at you, using their inferior assets (Unggoy, Kig-Yar etc) as bait, and other behavioral things. If they functioned as soldiers they’d work like ants, advancing in strategic pattern, establishing kill boxes, etc. For an alien to function the same as the Sangheili does it would have to fight like an independant warrior, not a soldier (yes I know a soldier can fight alone, no this isn’t a stab at our military, I’m just establishing that soldiers fight as one where as warriors are independant, but they can both be both ways, it’s only on default that warriors are independant and soldiers are a collaboration. I’m defining the Sangheili’s behavior and how it’s justified) and so I’m slightly worried that there might not be a “warrior” species, which would mean this element will be removed or unjustified, and because Halo is a series that likes to define and ground itself to some probability (I didn’t say practicality) I’d hate to seen one thrown in “just cause”.
The Unggoy were even unique in that they aren’t as important to the Covenant, in yet essential. What do I mean by this? With soldiers there is a measure of value for their own lives, this doesn’t mean it keeps them from succeeding, I’m just saying it’s present. With the Unggoy, their isn’t necessarilly. The Covenant use them in ways that contradicts basic survival. They’ll have them walk right into traps to wear an enemy down or will be used as diversions, where as soldiers don’t do this unless they HAVE to. With Unggoy, it’s what they’re good for, they remove the fear of direct approach by telling them that if they do not advance then the person behind them will kill them. Human soldiers have done this before, but they’re also valued, Unggoy aren’t they reproduce so quickly and are so abundant that sacrificing them is shameless. This threat tactic is allowed to work at all times because they are nearly 100% expendable, soldiers aren’t, not to the degree Unggoy are. I’m wondering if there will be a species set up quite like this in Halo 4 because an enemy would only behave this way under highly specific circumstances, and if they ran out at you “just cause” then it would make them appear stupid, rather than tactful. This isn’t to say that the Unggoy are smart, this is to say that the Covenant use them in a smart way. They are a great asset because they break the priority of living. In Halo 4 there might not be enemies like this which might end up making the game feel like a cover shooter if everyone plays behind cover and isn’t expendable.
The Kig-Yar are the most relatible in what they do. They don’t function as warriors and while being expendble they aren’t tossed out to wear an enemy down, expend enemy ammunition, or divert attention per say, they more or less “augment” a batch of enemies. While Sangheili are the warriors and the Unggoy and Kig-Yar are the tools of these warriors, the Kig-Yar provide a “perk” so to speak. Some units have Kig-Yar with energy shields. This gives the Sangheili cover while also allowing a direct approach. It also wastes human ammunition. But that’s all they’re good for, other than that they use the same weapons as Unggoy and while they are faster they do not possess a natural exoskeleton and are therefore less durable. Other units change it up with a Kig-Yar sniper, but the unit doesn’t “use” the sniper within itself the same way it uses the Kig-Yar with shielding. The only thing the sniper’s provide is pinning enemies, for the Unggoy advance, but that has to be met with geographical conditions in favor of such a tactic. While they aren’t warriors or expendable yet useful fodder they are perks to their team, and I hope there is an equivalent in the next game, for the Kig-Yar make for a lot of fun and tactful thinking.
That makes up the bulk, and the way they function is why they are fun to fight. If they functioned differently or if one was removed then it might not feel like “Halo” anymore.
