Robot Junkyards... Graveyards... Prisons... Whatever, these seem to be pretty common in Megaman after 7 was released I think... They often had stages that featured enemies from past games or previous stages in a destroyed/contained state.
Anyways, I get the chest upgrade, and I skip the heart tank since I seem to recall it requires the Crystal Hunter, and that's the only way to get it.
Also, more Dash Glitching.
