I have considered interesting to have some powerful infiltrator in my team.
I have created:
- Melee synedrion augmented torso
- Shadowstep synedrion legs
- Infiltrator head armor
- Weapons: Scyther, Shard gun (close combat ability), Crystal Crossbow
Together with frenzy state and maxed speed and willpoints it is absolutely unbeatable combo, even better than tech-assault.
