Frenzy is a style with a small set of weapons and utilities (each at infinite amount). Each turn lasts only 1 second, and the ready timer is set to 8 seconds. Retreat time is left at default.
In Frenzy, the 10 slot keys (F1-F10 by default) can be used to immediately select a weapon or utility. It is recommended to remember the 10 shortcuts. Note that some shortcut keys differ from the default ones in Frenzy.
Here are the slots:
|Frenzy slot||Usual slot||Weapon/Utility|
Note that opening the weapon menu already starts your turn (you lose your ready time), so the risk is high of losing your turn that way.
