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…

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