Beating Solus in Breakdown (Xbox) — General Tips

I can't play it for you, but these principles win the Solus fight:

• Learn patterns — 3-4 attack cycles; memorize telegraphs.
• Use cover — Pillars, crates break line-of-sight.
• Exploit openings — After his combo, 2–3 sec vulnerability.
• Weapon match — High-DPS rifle / shotgun for close; sniper for distance phases.
• Patience — Greedy damage gets you killed. Chip, dodge, repeat.
