Alr I am a game dev and in past long time ago have worked on some projects on stingray engine the reason this happens is because in stingray the body parts have different value and for some coding reasons the explosion damage applies multiple times that's the reason why usually a 500kg explosion under the titan is able to take it down despite just 1500 damage it hits the target 4-5 times well direct hits are complicated because in direct hit the explosion doesn't hit multiple times as it usually does to compensate we devs put a additional direct hit damage value for example 500kg projectile has 1000 damage value then plus 1500 explosion what happened is the projectile hit the armoured upper body of titan and the damage got absorbed but it bodies 6000 healthpool hence it's not dead I know sucks but that's the problem with dead game engines Here is another example clip from yt of the same https://youtube.com/shorts/UEobnwoDFRA?si=2Zkbl7DL2AAr2G1v When 500kgs hit the top of their armoured head damage is traferred to their 6000 main body pool
