I played Hard for the first time yesterday with 4 upgrades in each Titan.
It doesn’t just depend on the skill of the players but on the knowledge of the spawns and picking the correct Titan. On Hard War Games we managed to get up to wave 5 but we lost the Harvester. I had Scorch picked but he is a bad choice for this map because of the open spaces it presents.
But then Rise and Canal and Homestead came along. We kicked so much ass it was unreal. All that while I wasn’t able to talk to them. Since you cannot talk to your teammates, picking the correct Titan is mandatory.
This is how I pick em - Scorch - Never on War Games, Kodai, Homestead
Ronin - Never on Kodai
Ion - Never on Rise and Canal, the previous two Titans take so much better advantage of closed spaces
Northstar - She MAY be a jack of all sorts, super weak against Mortars and Infantry
Remember that Legion has long range and short range ammo. Go for Crits in order for Legion to inflict the most damage. Most of the times, that’s the center of a Titan’s face.
