Power of the Verse
Players are either Terrorists or Counter Terrorists, all having Peak Human to Low-Superhuman capabilities, reaching Wall level or even higher with weapons (Terrorists have access to C4 Explosives used to blow up a nuclear reactor). Soldiers by themselves are Below Average Human speeds while holding a Negev or a M249, being faster with knifes or while bunnyhopping which doubles their original speed.
