Bottle of water (or any other liquid)

[Ongka]

It wouldn't be too complicated, but some things aren't possible in hpl2 without changing the whole game code. Also, water which reacts to physics would be new in hpl2. Cause the water in the game is represented by a flat texture. The physics of a liquid itself would be way too much work to implement in hpl2 and would probably cause lags.

There are some ways to work around the fact that you can't hold the glass jar in your hand like the lantern, but they'd look bad and cause more bugs than useful gameplay.
