v1.1:

-Current settings are shown as a popup at the beginning
-Can disable forced sequence of weapons, enabling weapon spawns
-Can choose to activate a random mode, which choses one from Ranged and Melee presets
-Can choose to only use a preset from said presets, including a custom preset which can be edited by the user
-Ranged preset: pistol, revolver, assault rifle, sniper, m60, bazooka (in order, note its size is 6 --> 6 lives)
-Melee preset: baton, knife, bat, machete, chain, katana (in order, note its size is 6 --> 6 lives)

v1.2

-Added setting for infinite ammo

-Customization improved to modes:

-Normal Mode, weapon spawns enabled, no forced sequence, uses the user defined: lives, infinite ammo and melee damage

-Ranged Sequence Mode, weapon spawns disabled, lives defined by Ranged weapons preset's size, automatic infinite ammo, forced sequence from said preset, disables melee damage automatically

-Melee Sequence Mode, weapon spawns disabled, lives defined by Ranged weapons preset's size, automatic infinite ammo, forced sequence from said preset, enables melee damage automatically

-Random Mode, can choose from either of the three modes above, in which case their own rules apply

-Custom Sequence Mode, weapon spawns disabled, lives defined by the Custom weapons preset's size, automatic infinite ammo, forced sequence from said preset, melee damage is used as defined in script settings. Some script API knowledge is required for this part because you might want to edit this preset's array before using it.

Melee damage: on (can be changed by a Mode)
Infinite ammo: on (can be changed by a Mode)
Lives: 6 (only effective in Normal Mode, though the other modes also have 6 lives by default)
