Bow is definitely the weapon of choice. Katar not needed here.
This post has the fullest description of the ideal (including a potential upgrade line). It's a long post. Summarized:
This is a historic unit. Images of bas-relief, etc. are available.
There should be two crew - an archer & the driver.
There can be either 2 or 4 horses.
A possible victory animation would be for the crew to blow conches.
Post with picture. Can provide possible sounds if you decide to do this.
It would be nice to see the
arya symbol as part of the decor. This could be a good way to include civ color. The significance is that it is the Sanskrit for what the ancient North Indians called themselves. Incorporating the design as decoration provides a place for civ-color and emphasizes the "Indianness" of the chariot. At an earlier point in the project Michaelus & I discussed having the symbol mirrored on each side of the chariot -
looking sort of like painted-on wings. This might be a lot of work. Only do it if it suits you.
If you are willing to do a second version that would be the more mythological one. The only changes would be to make the main color of the chariot white or gold and to make the driver blue-skinned - as in the picture at the link above. The archer remains normal colored in this version. All the animations can remain the same.
Thank you, Shiro, for undertaking this.
