As a fencer myself and a gamer myself, I have to appreciate the combination of those two, merged into something that's exciting and fast paced. Although the game Niddhogg is the answer to what's coming up for the Steam engine and probably other gaming platforms.
Nidhogg is also another definition based on the Norse mythology of a dragon and I quote from the wiki source:
" In Norse mythology, Níðhöggr (Malice Striker, often anglicized Nidhogg) is a dragon who gnaws at a root of the World Tree, Yggdrasill. In historical Germanic society, níð was a term for a social stigma implying the loss of honour and the status of a villain. Thus, its name might refer to its role as a horrific monster or in its action of chewing the corpses of the inhabitants of náströnd: those guilty of murder, adultery and oath-breaking (which the Norsemen considered the worst possible crimes). "
However the Nidhogg game has some interesting imagery that reminded me of the modern retro game for the iOS platform called Sword and Sworcery, which I have a copy of. It has this muted color palette that's simplified, contrasting from the main game characters, especially the pixellated look that comes straight out of the 1980s era such as Karateka created by Jordan Mechner which I have fond memories of playing on the old school Commodore 128 and Apple II computers. The game Bruce Lee also comes to mind which is a classic. The latter seems much slower paced compared to Nidhogg, obviously due to technological advances of today's gaming platforms.
Nidhogg, I suspect, has this Dantean theme to it since duellists are damned no matter what the situation they're in, considering the background design and the environment itself.
I noticed that the game developers did a nice job, in the trailer, of using proper en garde positions for the duellists and using high/low guard stances wielding the rapier blades, if that's indeed what they are. I suspect they did some research within the fencing community or are practictioners themselves. So who knows? Otherwise, I'm very curious and excited to see this come out this month, a week before my birthday. It's going to be amusing.
Anyway, here are some screenshots of the retro-styled fencing game. Enjoy!
