 *  Cooldown Time : 480 Seconds (8 Minutes)

Gameplay Tips

 * Changing from the default "Safe" mode to the "Unsafe" mode gives multiple advantages to the user - with it being able to behead Bile Titans in 5-6 shots with accurate fire. Beware though, as charging for too long in Unsafe mode will result in the weapon exploding in the user's face.
 * The weapon can also be used to effectively engage Chargers by targeting their forelegs. Two fully overcharged shots from a railgun can break the Charger's leg armor, exposing the vulnerable flesh underneath and allows it to be finished off easily with small arms fire.
 * Against Bile Spewers and lesser Nursing Spewers however, it's best to aim for the head as the spewers can take on an impressive amount of ballistic damage.
 * There are 4 symmetrical orange/red visual indicators of railgun charge on the railgun, 2 on the back and 2 on the sides. They much easier to see in ADS (aim down sights) mode.
 * In safe mode, it takes about 1 second to "fully" charge.
 * In unsafe mode, it takes about 3 seconds until the railgun overloads and explodes.
