Team‑based mission mechanics — Missions requiring coordinated actions (e.g., two‑person button presses).
Daily quests — Small repeatable tasks such as “Complete 3 easy missions for 20k.”
Epic mission boss spawns — Chance for bosses to appear in epic missions.
AI Raid mission — Base‑defence mission where players hold off waves; turrets become valuable.
Fortress missions —
Fortress Easy: 2 convoys, 100 enemies, commander with unique armour.
Fortress Hard: 4 convoys, 200 enemies, multi‑stage assault, high‑end weapon/armour rewards.
Commanders have unique behaviours (dual R12s, sniper commander, aggressive LMG, grenade‑launcher commander).
Mission difficulty scaling — Encourage high‑level players to revisit lower‑tier missions via token systems.
