I've just had a gander into Outerra's core files, and it looks like there are some interesting assets that aren't being used at present. Included are:
- A dartboard projectile, complete with two separately colored dart projectiles (competitive multiplayer stuff?)
- A spear projectile
- References to a small array of alternate characters, to include a horse
This means the features/content in question are either: A. old testing stuff left over from things the devs were trying out but that never made it particularly far, or B. new or newer testing stuff indicating still-work-in-progress features that are likely to enter an upcoming update. I guess the million-dollar question is: how old
is this content, exactly?
