Nintendo has sent out a teasing fan survey, detailing the long-awaited Pikmin 4.

In it, Nintendo asks respondees to rate their knowledge of the Pikmin series so far (fairly strong), their impressions of Pikmin 4’s recent marketing (it’s been OK), and what they’d be keen to hear more about as its 21st July release date nears.

This last part is most interesting to me, as it touches on a few features Nintendo has only hinted at so far. This includes “delving into puzzle-filled caves, and carefully managing your resources until you escape” plus “embarking on night-time missions that feature new and intense gameplay”.

Caves were shown briefly in Pikmin 4’s latest trailer, though it was unclear how much they might feature. Pikmin 2 used them extensively, and it appears the mechanic of going in with a set number of Pikmin and trying to make it out the other side is back.
