The predators did look like those, and so were Striking Scorpions
I think the warriors were wraithguards (but they never got out of the bloody tank)

(these were in one tank - the missile troops in another)
The Jetbikes were the last pics you put up. Most of the time they were "fortuned" and even though they took quite a lot of shots from my necrons, I never managed to kill one.
Nice pics by the way
Sorry for the lack of detail, I can do somewhat better.
Eldar started and deployed at the end of the table near a fortification.
Necrons deployed in the middle of the table with the lord and warriors, near the edge (to contest the fortification) with another unit of warriors and the scarabs - and I put in the destroyers as reserve.
Turn 1
Tanks moved in and shot at the warriors without the lord
jetbikes shot at the lord's unit.
Very few casualties from the Necrons.
My go - I VoD towards the jetbikes and opened up with rapid shot. They saved all rolls due to "fortune"
Scarabs jumped a tank and necron warriors rapid fired at it in an attempt to glance it. Decent rolls to glance, rubbish for damage - gun was left non-operational for one round.
Turn 2.
Tank with wraithguards moved towards my necron lord, jetbikes shot - then assaulted the lord's unit (thinking to trap him into combat)
Little damage to necrons.
My go - VoD out of combat (unlucky roll left me out of range to shoot)
Destroyers entered and shot at jetbikes - they saved all hits.
Scarabs and necrons shot at tank again .... again, disabled gun for 1 round.
Turn 3.
Eldar missile troops get out of tank and shoot at my necrons. 3 dead
Bikes move away from my lord's unit and assault with scarabs
Tank with wraithguard moves towards lord's unit and destroyers
My go - destroyers shoot at incoming tank - disable gun for 1 round
Lord's unit moves in and rapid fires on same tank - disable gun for 1 round.
Turn 4.
More Scarabs killed by bikes
Eldar missile troops shoot - then assault my necron warriors. Few more dead.
Tank with assault troops moves back to the bikes to provide cover
My go - port over to one of the tanks with Lord's unit - rapid fire ... gun non-operational for 1 round.
Destroyers do the same .... all saved.
Turn 5.
Wraithguard exit vehicle and assault my necron warriors already being assaulted by the missile troops.
NEcrons do surprisingly well and don't get swept.
Scarabs finally killed by bikes (eldar score a kill point)
My go - nothing to shoot at other than tanks ..... Port over to tanks and rapid fire .... you guessed it .... weapon disabled for 1 round
Lord leaves unit to assault the tank with warscythe. Guess what happens? Weapon disabled for 1 round.
Necron unit continues to fight a losing battle against wraithguard and missile troops.
Turn 6
Necron unit under assault eventually gets killed off. (Eldar now on 2 kill points)
Tanks fire at remaining necrons ... do very little.
My go - Destroyers and warriors shoot at the missile eldar (now they are not in combat) Manage to kill the unit (Necrons 1 killpoint)
Lord with warscythe tries to nail the remaining tank for a draw ....... weapon disabled for 1 round ...... grrrrrrr.
Eldar win ! (Boooo)
