Ah, pity. I guess repulsors and firepower all the way then.
We also don't have Repulsor
weapons; they're only being used as drop-in replacements for the jetpack, to give us effectively infinite jetfuel. We do, however, have...
Current Mounted Armament:
4x Hasta Autocannons on arm mounts
2x Pilum Mk II Missile Launchers w/ 3 rounds each on side shoulder mounts
2x SMG Turrets in AMS configuration on top shoulder mounts
...the
worst possible configuration for fighting a single biotic infiltrator. In particular, we have no Sagitta mounts, which is really rather silly, since there's really no reason to have 4x Hasta autocannons installed; one wonders why we had a Legionary set up this way to begin with.
Well, only way out now is through:
[X] You're in a perfect position to intercept the biotic super soldier. You stand the best chance against him with you upgraded Legionary.
Though your combat skills themselves aren't the best. We've managed to beat a squad of Legionaries practically by ourselves before; one guy shouldn't be that much of a problem, but best to be cautious anyway.
-[X] Get high, and get far; you're fighting a biotic, and biotics don't tend to go for range boosts. Fire 4x Piliums as an alpha strike, and go 3D by using your Repolsor jetpack to get on the roof of one of your multi-story buildings (using the building itself to cover your movement), where you have the high ground, cover, and enough distance that your weapons can hit, but the enemy's biotics won't be able to reach you, or even see you.
--[X] From there, massed autocannon-fire should do the job; duck behind cover to dodge biotic abilities. Bring up your Barrier ability if it does not interfere with your shields.
[X] Have Security send a runner to activate any idle Tigers in our factory, waiting for shipment. Call it a secondary Quality Control test.
Seriously, some Barriers stack with ME shields; some overlap/replace. I don't know which one we have.
