Even the plants on Pandora are deadly. The hostile, bare climate here doesn’t offer much to sustain vegetation, but still some persists. These plants, like the wildlife around them, have developed harsh defense mechanisms, one matching each major element.
Stinging Cacti arc shield-sapping electricity around them when provoked.
Firemelons explode if anything hits them, splashing flames all over the surrounding area.
Necrophage plants release homing, corrosive spores if disturbed. These bulbs seek out the nearest enemy and collide with them, spreading caustic fluid.
Other Hazards
You’ll also find areas outright flooded with Slagged fluid, or corrosive ichor, or molten lava… suffice it to say, tread over these surfaces at your peril—you will begin to feel the effects immediately, and your shields and health will only hold out for so long while exposed to certain hazards.
Barrels of various elements and explosive gas cylinders have been left around as both supplies for and by-products of various industrial sites on Pandora. Their effect will match their color. Yellow are simply explosive, red are fire, blue are shock, green will corrode, and purple are Slag.
EXP Loaders and Suicide Midgets bring the boom right to you, like barrels that want to be friends. Similarly, some Nomads are equipped with pack technology that works much like gas cylinders and barrels. Shoot the pressurized gas canister on a flamethrower-wielding Nomad’s back and it will explode, killing him and probably anyone near him; shoot the electric capacitor on the back of a Shock Trooper Nomad to cause his arc projector to go nuts, electrocuting anyone nearby. They are like mobile barrels.
