Yeah, Redskins itself is a derogatory term for Native Americans, so the naming convention of Deadskins, while it lends to the whole undead Indians motif and is admittedly a little clever, could be construed as offensive.
Not necessary done with malicious intent at all, it sounds like Christopher Garnaas (the lead on the project) just has a concept he has faith in and wants to make something out of it, but I think with the unsavory historical association of the term, it is objectively a little ignorant of him and thus would be legitimate for some groups to be offended by it.
In the end, it comes down to who is using the term, how are they using it, and why. In Deadskin's case I want to say it has some small details in the campaign that are really questionable, game modes like "Capture the Scalp" really don't scream to me that they're trying to put Native American culture in a positive light, but I guess for the time it's set in it is something that did occur, and that you play as American Indian warriors fighting against a more vilified force in that it's a bunch of ruthless zombies, I guess it could be worse, but I feel like it's asking for trouble in a lot of places. I just don't know that making a whole game mode out of scalping a dude for the sake of avoiding just using a flag or different alternative is worth the controversy.
At the same time, it'd be unfair not to take into account that they're working on the project to try to entertain people with a unique approach to a zombie game, not tear down Native American culture. It certainly doesn't flaunt itself as an accurate portrayal by a long-shot XD
Visually it's definitely an eye-grabber with all the neon mixed in with the Wild West era setting (a bit of a confusing combination, but they did a decent job with it) and the gameplay, though pretty early and slippery-looking at this point, could definitely develop into something good. If there is any significant story, as long as it doesn't turn out with you fighting Giant Zombie General Custer while he spouts racist one-liners and fires cannons at you it should be okay, but yeah, this is one project that, granted it gets funded and/or developed, (I guess it's early to say but it seems the project's had a really slow start for its lofty goal) will need to tip-toe delicately around this sort of controversy when it comes to light with more public media sites.
Sadly I think this is the kind of stuff that's bait for media to latch onto and point fingers at for some controversy stories, so if they get funded they'll have to strap in for a bumpy ride with their PR interactions.
...Sorry I kind of derailed the purpose of this thread for a while there. I think I need a better outlet for my writing binges. X_X
