Well, they have taken cylinder head bolts that run to the crankcase
and made them into moving parts, essentially. Not too bad a deal,
since it does keep things compact, and the port timing is sweet.
The Napier Deltic was another notable opposed-piston engine.

Hi Pete
Eco motor is innovative modern IC engine evolution
You can see video , animated pictuures too
http://www.ecomotors.com/
The opoc® engine comprises two opposing cylinders per module, with a
crankshaft between them -- each cylinder has two pistons moving in
opposite directions. This innovative design configuration eliminates
the cylinder-head and valve-train components of conventional engines,
offering an efficient, compact and simple core engine structure. The
result is an engine family that is lighter, more efficient and
economical, with lower exhaust emissions.
..the big news here is they combine the best features of VW-style
boxer engines, with those of the Junker Jumo diesel aero engines,
but carrying the piston loads directly thru the conrods to one
crankshaft, rather than Jumo-style from 2 crank shafts thru the
engine block and thru Jumo-style idler gear trains to the propeller
shaft. Slick. :o) Now, I wanna see a Junker response. ;o)

Scenarios always come in sets of three:
best case, worst case, and just in case.
