[FEATRUE] Interactive environment - gas, fire, oil, water

[kreghek]

Problem

Now have only one challenge - the luck during a roll to hit. The person must hits a monsters first to survive. This is not interesting. The player have no additional interesting instruments to win in fight.

Solution
We should add interactive cells filled by some elementals.

Examples:

• If throw a fireball to a gas - it exploids and damages all persons in its area.
• If throw a lightning ball to a water - it damage all persons and stun thier.
• If hit water steam cloud by electro-stick, then it stun all enemies inside the cloud.

Looks like traps planned in the game.

Possible subtasks to complete this experiments (add task number after creation):

• Static objects to repesent gas, water, file, etc. Static objects can damage. They must be passable.
• Add a few of equipments with true elemental damage - napalm, ice/storm wards, granades, flamers, spreader of some liquids.
• Add a static object module to exploid or making other effects to the persons on or near the static object.
• Add some person effects like flaming, shock/stun, rusting, freezing.
