HLKILL

Gordon's whole arsenal, V1's hell. HLKILL adds every Half-Life weapon to every ULTRAKILL level, next to V1's own guns, with their real models, animations and sounds loaded from your own copy of Half-Life.

The guns

• 7: Crowbar.
• 8: 9mm handgun, .357 Magnum. Right click on the handgun fires fast and loose.
• 9: MP5, shotgun, crossbow. MP5 grenades on right click, double-barrel shotgun, scoped crossbow.
• 0: RPG, Tau cannon, Gluon gun, Hivehand. The Tau fires Half-Life's orange beam, glancing off walls it hits at a shallow angle, and a charged shot (hold right click) fires a thick white one that knocks you back. The Gluon beam stays on while you hold fire. Hornets home in and grow back.
• −: Hand grenades, satchel charges, tripmines, Snarks. Satchels go off on right click, tripmines trip on an enemy crossing the beam, and Snarks hop after enemies and bite until they pop.

Press a number again to cycle through that slot.

Play it the Half-Life way

Every shop terminal gets two switches under Sandbox, and your choices are saved:

• HALF-LIFE ONLY takes V1's guns away and leaves nothing but Gordon's arsenal.
• HALF-LIFE MOVES makes V1 move like Gordon: no dash, slide, wall jump or slam, with Half-Life's run speed, jump and air control. Hold the dash key to sprint. Gordon's footsteps (quicker when sprinting), jump and landing sounds come from your Half-Life.

The HEV suit and HUD

• The HEV suit talks, in its own voice from your Half-Life: it names each weapon the first time you draw it in a level, calls out ammo pickups, tells you when you're out of ammo, and warns when your health drops.
• HEV armour: enemies drop HEV batteries, and armour soaks up most of each hit like Half-Life's suit ("power level is forty-five percent").
• Flashlight on V, with Half-Life's click and a battery that drains and recharges.
• Holding a Half-Life gun brings up Half-Life's HUD: health, armour, V1's stamina, the flashlight battery, and Half-Life's weapon menu when you switch guns.

Half-Life rules

• Clips and reloads (press T; R stays ULTRAKILL's whiplash). The shotgun loads shell by shell.
• Limited ammo with Half-Life's maximums, shared like in Half-Life.
• ULTRAKILL's enemies drop Half-Life ammo boxes when they die, more from big enemies and bosses.
• Half-Life's orange ammo counter, and Half-Life's weapon icons in ULTRAKILL's weapon HUD.
• Kills, headshots and multikills still earn ULTRAKILL style.

You need
