Unlockables

There are many things in Gamecraft that can be unlocked by completing a certain task in-game. These things are very useful in messing around the world or creating comedy machiminas, but otherwise cannot be used in any form of map-making. But if they are acquired by hacking, the Gamecraft Engine will delete the world in which the object was hacked in.

Jumper Weapons
The Jumpers (Rocket Jumper, Grenade Jumper, Sticky Jumper, Tri-Nitro-Jumper, Nuke Jumper, etc) is a set of weapons that allows players to explode their feet and get propelled without taking damage from the explosion, but does not prevent fall damage.

The Jumpers can be unlocked by performing 100 Explosion Jumps in a row without dying.

Dr Hax
Dr Hax is a Neutral Mob that throws PC Monitors at hackers and those who attack him. He will yell "HAAAAAXXXX!!!" and launch a Monitor at his target, which causes death regardless of the victim's HP.

Dr Hax can be unlocked by beating the Block Life game at least once.

Hax Gun
The Hax Gun is an ability used by Dr Hax to punish hackers. It consist of the user pointing in front of him (female players cannot equip this), yelling "HAAAAXXXX!!!" and launching a death inducing Monitor.

The Hax Gun can be unlocked by killing Dr Hax in any 3 different ways without getting Haxed.

Death Radio
The Death Radio (AKA "Boom Box of Doom" or "Erectin' a BOOM!") is a radio that, when played, lights any nearby mobs and NPC on fire. The player can select the music to be played before actually activating it. The player can also add their own musics into the folder "Death Radio musics" and have it played in game.

The Death Radio can be unlocked by earning all Engineer Achievements in Craft Fortress.
