Yesterday I completed my first Legend campaign (after another three playing Veteran) , I played 7 days, ODI was 80+ , March 10 in the game.
I finished the game with 19 soldiers, but I used only 14 for the missions (the others for SP pool), and I suffered only a few casualties.
In the beginning with only 4 squaddies and Phoenix weapons, missions were interesting, injured soldiers almost every battle. Limited resources destined to better weapons, new facilities, also reverse engineering, and new “naked” soldiers needing armors too.
So every mission was a challenge, even nests in the dark. Creating a “full” 6 squad took time. Random distribution of bases(South America without base, the closest point, Canada) and diplomacy missions locations to unlock havens locations(REP25) increased the time to complete the campaign.
Only one Manticore to control global threats, haven attacks, scavening missions… put strees in my small troop, but manufacturing a second Manticore and putting together a second Squad for scanning and “low risk” missions midgame was the turning point.
After that with better weapons, and skilled soldiers, some of them Multiclass resources were coming “easily”, I ended with 4 aircrafts, 2 Manti(soldiers recruiting/transport and commerce) and 2 Thunderbird
The curve is there, difficulty present in the beginning, mid game, but at some point 6 skilled/armed to the teeth soldiers will wipe out 15-20 Pandas included Chirons/Scyllas without batting an eye.
This time I created different Multiclass combos, Assault/Priest, Sniper/Infiltrator… Assault/Heavy with +30% damage was a blast using Deceptor MG and RB, Big Bosses killer, added augmentation and Thor AML, totally OP.
About skills, Rally was not necessary, I used in Extreme missions once or twice, but not always.
Never used double dashing per turn, or speed beyond 20-21. Rapid Clearance is extremely useful and Priest level 7 is cool, but I prefer Technician , Multiclass from the beginning (deploying turrets + healing), I didn’t need to use Electric Reinforcement
Final mission wasn’t different from Veteran LV, I expected more spawning, resistance, my soldiers reached Yuggothian Receptacle without a single scratch (technicians patched a couple of lightly injured snipers due to initial Chirons)
