As for Half-Life, it’s unique weapons gives players lots of awesome expriences. Now all the weapons in Half-Life 1 has been re-made into Minecraft in LambdaCraft. Most of the weapons use techne model and can use both left&right mouse to shoot, without interrupting running and sprinting. Hope you’ll find what you felt in HL in LambdaCraft ^^

2.Tools and Euqipments

In Half-Life, you must have a deep impression about the H.E.V. suit that Gordon Freeman wears. In LambdaCraft, we also added lots of stuffs about H.E.V into it, including the suit itself, health charger, armor charger……As for the suit, it can absorb large amounts of damage, and some attachments can be attached to it( Ammo managing, Longjump, Defense upgrade, … ).Also, the head-up display is what you must exprience…

Health Charger

Classical element from Half-Life.

Provides health recovery and side buff. Put instant healing/recovering potion in slot 1, and put other kinds of positive effect potion ( Except instant ones ) in slot 2.If the machine has stored some EU

, it will drain potions into itself. press F( or Use Blocks key ) on it, and you health will recover in a great speed. Also the buff in slot2 will be provided to you. P.S. all potion added into Health Charger is calculated with 1.2x original time.

LambdaCraft Mod

Medkit FIller

This name is rather stupid I suppose (Will be changed in the next version)

put your medkit in the upper slot, and put potions in the three slots below.

The machine will start putting potion into your medkit with speed of 5 secs per potion and 7EU/T per potion.

For time effected potion, effect time is 1.2x original time.
