Nails buys an AWP for primary weapon and the Dual Elites as secondary weapons. If unaffordable, he buys a Scout and followed by a Galil and then a MP5 Navy as substitutes. He does not buy or pick up other weapons.
Nails is a quite passive bot. He will retreat after spotting a large group of Counter-Terrorists. He will find a suitable place to camp and then wait for enemies to come. Upon the presence of enemies, he will kill targets one at a time. In hostage rescue maps, he prefers to camp near the hostages.
