Latest update added a new difficulty panel with 5 difficulty modes, the old difficulty panel is now called difficulty modifier which alters the damage you deal and take. Easy modifier increases damage dealt by 50% and reduces damage taken by 25%. Hard modifier reduces damage dealt by 25% and increases damage taken by 50%.
The difficulty levels in a new panel affect baseline hp, damage, accuracy, ammo and health amount.
Hard Diabolical is: 52-67 damage zombie melee attacks, 30-52 antlion melee attacks. 170-260 damage spit attacks and 30 damage headcrab attacks. Basically don't get hit at any cost. My aim is sloppy and I forgot to use my grenade launcher when I needed it, but I didn't die too much yet. Enemies are also tanky as all hell in this mode. In this difficulty mode the player is barely more durable than a rebel when at 100/0 hp/suit. With max health and armor the player is barely tankier than a combine soldier. At 100/200 is barely tankier than an elite soldier.
General strategy for vortal coil defense is to use gravity gun extensively at later waves, any bullet will kill exposed antlions. Use .357, buckshot and smg grenades to clear the caves. Use props to deal tremendous damage.
