Narrative:

I started my descent into [descent] as normal. Once; I established communication with tower; they advised me to take the right downwind for 34R. I had already had my flaps deployed while trying to get established from my descent and into the traffic pattern. Everything was going as a normal controlled landing should be. I looked down to confirm that I had 3 green; it appeared as I did. I continued on with the approach; tower then cleared me for [a different runway] instead. I came onto final; everything was looking perfect. Once I touched down on the runway; the wheels hit the ground soft and felt like a normal landing. I slowly eased the nose down as I was still in the process of the landing phase. As soon as I did it felt like the wheels collapsed and the props started to hit the ground. As soon as I heard the props hit I killed both engines. Looking at the aircraft on the runway; my opinion there was limited [damage] to include: ground damage; nose landing gear; minor damage to step; and as such does not rise to substantial damage per far. Once the aircraft was towed to the FBO; and runway was cleared I called tower and asked if there was anything [they noticed] with the landing gear. They stated that they looked and verified by binoculars that is was indeed down.
