SKULL-11

Skull-11 is the final anti-zombie weapon built by the Rex Research Institute in Counter-Strike Online based on the Korean-made USAS-12 shotgun.

Overview
The Skull-11 is an anti-zombie shotgun that fires 28 rounds of 12 Gauge Anti-Zombie shotgun shells that deal critical damage to zombies. It is also widely used in middle-ranged combat due to having an enhanced slug mode as its secondary fire mode. However, the Skull-11 cannot penetrate walls or objects making it a huge disadvantage over the other weapons in the Skull series.

In Zombie scenarios

 * Skull-11 is very effective at clearing crowds of zombies with buckshot mode.
 * Recommended when facing Juggernaunt due to his large hitboxes.
 * Not recommended when facing Ganymede because Skull-11 is very heavy, it need proper skills to dogde his rush attack and the pellets won't do much damage if using buckshot.
 * Not recommended when dealing with bosses in middle/ far distances, because the pellets won't do much damage.
 * Slug mode is not recommended due to low rate of fire and no penetation.
 * Skull-11 can break barriers easily.

In Zombie mods

 * 28 rounds of Skull-11 can deal about 3136 ~ 6272 to zombies.
 * Use it in ducts/closed areas for maximum performance.
 * Combine with Deadly Shot for massive damage.
 * Combine with Nata Knife / Skull-9 / Hammer if you have proper skills.
 * Aim for newly infected / common zombies as they're weak and can be killed easily in close range.
 * In close range, aim for the head or chest for maximum damage

In normal matches

 * Not recommended in Original because it is very expensive.
 * Recommended in Deathmatch/Team Deathmatch/Basic/Item Battle,... mode, because it can mess up your opponent aim and has high stun power when firing continously at enemies so that your enemies can't escape.
 * Ideal when dealing with large ammounts of enemies.
 * Note that Skull-11 can penetrate Kevlar, use it as an advantage.
 * It is very powerful in close range and has high rate of fire / ammo, closed maps such as Italy/ 747 / Estate,... is an ideal place to use Skull-11
 * Switch to Slug mode when dealing with enemies at far distances.

Normal modes

 * They're slow and have long reload speed, but deadly with their 28 rounds of 12 Gauge Anti-Zombie in close or middle range. be aware of their appearance in closed maps such as Italy, 747.
 * In middle range, 5-7 shots from Skull-11 users will mess up your aim and stun you, or even kill you. so try to annihilate them quickly.
 * In long range, they have to use Slug, so the rate of fire is slow, use this as an advantage
 * Suprise attack is recommended

Zombie Modes

 * Skull-11 can't dig through walls or obstacles, so mostly you'll survive and can protect your zombie teamate if you have a massive ammount of 8000HP and up if you're in Ducts.
 * Skull-11 have massive knock-back power if you're in mid-air and high stun power when you're on ground. use Heavy-Type zombies instead.
 * You can't run when being shooted at, Skull-11 will stun you if the shooter hit you repeatedly and other humans will have a chance to melee you, jump when being shooted at to escape easily with Light Types.
