Quickly brainstormed suggestions:
- Firstly, I don't really see that knife there. With the infinite ammo and - if you've seen some of the most action-packed western movies - action-y reloading of the revolver, what would be the use for the knife, except for the uber-damage. I imagine the Halo scheme here, and in the kind of game you're talking about, that button for quick melee should already be occupied.
- Secondly, I don't think you should throw in a suggestion of multiple types of Warlocks and their disguises in such an off-hand way. How, all the description before that was implying the close resemblance to SotC, and bah, there are more types, and they are not monstrosities at all! That's either really unbalanced, or misleading. Maybe, if there are a lot of NPCs (steam-armada, various drivers, city inhabitants) and enemies are a hodgepodge of elements and races, then it's not so similar to SotC?
* to be considered completely as well-wishing suggestions.
Yeah, these need addressing. For the dagger, ideally, it wouldn't be 'uber damage' in the same way that physical attacks in Halo are, but it would allow you to deal damage quickly in the hands of a skilled player, more like an RE4 professional. The dagger, as I mentioned, has the duel purpose of being able to defend and parry attacks, which would be necessary against foes that attack so relentlessly that stopping to reload a gun is hazardous. Also, I think it would be prudent to include enemies which are naturally resistant or immune to gunfire for reasons like forcefields, or just being fast enough to knock the bullets out of the air Afro Samurai-style, thus necessitating the dagger's use.
For the second bit, this is more of a problem with my lack of a suitable diction. When I say "Monstrosities", I'm using it as a general term for the magical vessels which the Warlocks use. I was tempted to refer to them as creatures, but that's inaccurate as they're not living. I was tempted to call them monstrous vessels, but that's misleading. I thought of calling them magic robots, but that's just misleading as well. I thought of golems, but they're not all giant stone creatures, and golem evokes the image of big stone people, which only one is. I was tempted to call them colossi, but I can't reasonably draw parallels between them and my imagined creatures and expect people to understand what I'm talking about when I deviate from that. I settled on using the word "Monstrosity" as a means to conveying the game's general tone towards them, that they're thinks that a definitely unnatural, horrifying, and destructive. While SotC is an inspiration, it's not the only thing that's fueled my imagination to make this idea is what I'm trying to get at.
With that said, I think it should also be noted that when I say "Warlock", I'm also using that as a general term for these magical people. They're not big wizardy-looking Gandalf people, but immortal humans that have modified themselves to be better warriors.
I think the best way to let you know what I'm talking about would be to just try to lay out the progression of the game to the best of my ability, and detail the individual Warlocks and Monstrosities that they control, and their abilities/personalities.
