Data Packs are found in ACSIS, under Simulation, they're unlocked from Chapter 3 and you need to beat 2-4 enemies a pack to unlcok the achievement. You'll also get emblems, schematics and sometimes a part.
Generally you'll need to float above the enemy NEXT and bombard it, then if you miss you'll still do Splash Damage. Use the small green level 2nd from bottom, it has a floating cross in the centre of which you'll start at the top and offers plenty of simple tactical options. Most enemies you'll want to keep up top, but some are better fought at ground level and some under the structure.
I use Regulations 1.6. (Except on Jan in ALD-MEL Pack i use 1.0)
Mary - Hard. Need to try and float above her, but not too high as she'll sit right below you, try and be about 2 mechs above her before bombing her with OGOTO's. May take a few goes. Same NEXT as Empress Story Level.
Wong - Similar to Mary, float slightly above but he'll sit back a bit so you can easily finish off at mid-range.
Unseel - Easy 'tank' style NEXT a nice slow fat target . Float above and bomb him with OGOTO's, his weapons have high stun so use RT to doge.
You'll get a Sniper Rifle for finishing this Pack.
