PC.IGN.COM previews Seed, an upcoming first-person action game from Human Soft (thanks Billy at VE). Here's the article's description of Seed:

While these screen shots make Seed look like it's another first person shooter, in fact gameplay more closely resembles a platformer than anything else, although there is combat involved too. In fact, the best analogy is probably to Montezuma's Return, another first-person point of view game done in a 3D engine and with a mix of jumping hazards, environmental puzzles, and combat.
