Lunatic appears in all missions of easy difficulty. He is not encountered in other difficulties.
Lunatic's skill type is easy, which means he is 0% accurate when firing, has a reaction time of 0.5 seconds, and cannot detect footsteps. When facing an enemy target, he will hold fire for 1.5 seconds.
Lunatic buys a random weapon for his primary weapon and the Dual Elites for his secondary weapons. He will pick up the M4A1 if discovered and uses it without the silencer. This is because Lunatic's weapon preference is the Maverick M4A1 Carbine as defined in the BotCampaignProfile.db, which is not available to the Terrorists.
Lunatic is part of the Guerrilla Warfare.
- In the file "BotCampaignProfile.db", at the line where Lunatic can be found, it has a description of " WeaponPreference = m4a1 // kind of a hack - give him a weapon he cant buy so he uses pistols". It is possible the developers intentionally put this for humor or wanted this bot to only use pistols.
