The sixth category will contain three tools:
Big thanks to user Wojacket for discussing new main features and correcting some logical mistakes.
So, what new weapons are planned:
Sliding blades (Her first weapon, which is built in into her body)
Semi-automatic pistol (Like Alyxgun)
Pulse battle rifle (A small and more rapid version of pulse rifle)
Tau-cannon (Given by a Black Mesa scientist before entering a dangerous zone)
S.L.A.M. (Radio controlled mine)
MirageStar Pulse Rifle (Replaces Combine Pulse Rifle, but works similar. This prevents spoiling Seven Hour War scenes in this mod)
Pheropod might be removed.
What weapons MUST be one-handed, and it can be used to shoot from both hands:
More possible, that most weapons will be one-handed
More mobile movment model :
A new movment model will be more mobile and light. Elina AT-04 can sprint faster than Gordon Freeman, and she can sprint as long as she want (No aux power required for sprint). Also her movements must feel very light, she should "fly like a butterfly and sting like a bee" (Gordon looks like as a heavy, armoured solider).
Jump higher. And jump two times.
Also, Elina jumps higher (from half to one her height). Plus, she can do a double jump - first jump from a platform, and do a second jump mid-air.
Two camera modes
The camera should have two modes: first person and third person. FP mode should be default.
A new HUD:
The hud will remind us Half-Life 1, but it won`t copy nor HL1, neither Black Mesa and HL2. It will be centered, and it will have damage type indicators and a compass.
A new damage type:
So, the season of mod`s story is cold, snowy winter. But wait... It won`t be logical, if Elina won`t be able to get freezed over. So, there`s a new damage type: Freeze Damage.
Textures, particles, effects, etc.
And certainly, new, winter textures and effects.
Inspired by EEgle-RU's story: Metal Hearts, as well as his old mods, Half-Life: Symbiosis will consist of custom content and other Source content, but remain a Half-Life 2 mod.
