That's where the challenge is...

Try to make it look good, try to make it look interesting and full of
detail.

Like under water plants, fish, water bubbles, big water bubbles of
explosions.

There are probably no games out there that really do it well, so it might be
an under developed graphical thingie.

Though I do remember "future shock" or whatever the game was called, but it
was a fantasy game and there was just somewater going through corridors...
I never really played that game...

But for a game like Battlefield 3 there could/should be some more than just
"fog" and a flat ocean bottom or no surface at all...

Perhaps sea-creature-shells can be added to beach for extra beach details,
perhaps ocean/sea/beach bottom as well with more detail.

Soldiers could even get hurt by swimming to close to sea correl which might
cut them up.

There could also be maps with big builders in the beach sea or air/sea
tunnels which can be swim through.

Come to think of it Call of Duty 5 had a special "water splashes" effect
which was pretty cool and most rememberable.

Rumor has it that it only worked on nvidia cards and not ati.

In the far future say 15 years from now, devices might be so powerfull that
lightning and glass/water effect/reflection could even be calculated... and
water would be dripping between soldier fingers and over their heads when
they come out of the sea...

So there is still a lot to be done at that front !

Even rainbow effects of water splashing against the sides of a harbor might
be possible or so
