I also have an idea for a raid encounter. Dyra'an, Siege Commandant: Part 1: [spoiler]This would be the raid's start, in a dusky red Martian valley. In the valley's centre is a hexagonal Cabal machine structure. Upon someone getting near the machine, Cabal start to flood the valley, dropping in from Harvesters. In every Harvester, a Scout Infiltrator (a type of Psion) will spawn. Half the team have to hold down three plates at equidistant point around the arena. With all three active, the machine will start to glow. The other half have to find and kill the Scout Infiltrators. They are small and their aim is to run up to Guardians and use their shockwave, which immobilises you for a short time. Killing an Infiltrator gives you a Security Pass. Once all three people have the Pass, they need to meet at the central machine. With all three standing next to it, and the other three on the plates, the machine will start activating, using up the Security Passes. This process then needs to be repeated. When 15 Passes have been used up, the machine will activate fully, lighting up green. All 6 people now need to stand around the hexagonal structure. One person has to insert their Ghost to hack it, then all will be fighting a large wave of Cabal. If one person steps away from their side, the machine will take longer to hack. After an optimal time of 90 seconds, the machine will power down and descend into the sand. Loot is given. [/spoiler] Part 2: [spoiler]Large double doors open and Dyra'an, Siege Commandant, charges out. He is a massive Centurion type with bulky silver armour. Four Harvesters drop a Tank from the sky and Dyra'an enters it. The battle starts. The first phase of the fight is simple survival. To get Dyra'an to the next phase you have to wait. Unfortunately, this means in this time he will charge at you in the Tank, summon Cabal, and be difficult to avoid. After a few minutes, the plates from the first phase will appear again, now in random spots in the valley. Three people need to run to a plate each. This will cause a beam of light from each plate to hit the Tank and follow it. The message "Cabal network accessed" will appear. To get Dyra'an vulnerable, you need to lure him onto the central machine while the beams of light are upon him. One person should get his attention by shooting his legs, then stand on the centre to get him to charge at them. If this succeeds, the beams of light will intensify and the Tank will spark, becoming vulnerable. The message "Ghost hack successful!" will appear. During the 30 second damage phase, the Tank will randomly charge around the valley, forcing you to be constantly mobile. Both Dyra'an's head and the Tank legs are critical spots. Repeat at least 4 times (he has a large health pool) to destroy Dyra'an. The Tank will destruct, forcing you to find shelter somewhere or risk dying. Loot is given. [/spoiler] Challenge Mode: All enemies but Dyra'an must die before the beams of Light are activated. This means a far more hectic first phase, as you only have a few seconds to get on the plates when they appear before you wipe.
