Great followers of Hypovolemia.

This is what you can expect in HYP 0.5

( We are no longer calling this version 0.2 )

- Many guns have been added.

- Handgun model blowback animations.

- Optimized server-side ragdolls for faster networking, as a result - ragdolls now appear to move faster, suddenly and more violently.

Curb stomping is now a possible method of execution, by repeatedly jumping on top of incapacitated bodies! *death by trampling is possible

- Character Randomization

In Free For All, everytime you spawn, a random model will be picked for your character. Skin and body groups are randomly chosen.

While in Team-Based-Modes the randomization is more narrowly set for each Faction.

- Networked inventory system.

  • Ammo and ammo containers are now accurately weighed. Asymmetric balancing with US and RUS faction. Accounting for "Firepower and Less ammo" vs "Fire Rate and More ammo" dynamics.

Firing heavy caliber or grenade based weapons will now noticeably decrease weight per shot.

- Improved sound

  • new custom recorded footsteps sounds for all default materials.

  • increased the amount of custom surface props materials for variety.
  • Bullet whizz sounds if tracers near miss you. * sounds made already
  • Bullet impacts can now be heard just as far as gunshots.
  • Bullet impact sounds now have a different realistic sound for distant echoes.( Distant concrete can be heard being slapped, instead of sounding like it's happening next to you )
  • All new vox from being incapacitated, hit by explosives, arm shots, bleeding to death or actually dying. Screaming is heard interrupted mid gibbing.

* Improved Physics

  • Push forces for world objects is now scaled per weapon.

( I.E. Railgun will fling barrels across the room, or in many cases instantly gib the prop and send the gibs flying at high speed )

  • You can expect manual weapon handling for all rifles and handguns now and not just shotguns like before.

Upper-Receiver/Bolt-Carrier/Slide racking, audible cues that give your position away.

With rifles it's possible to do a quick reload by skipping racking, if you change mags before expiring the last bullet.

Equipment Changes:

  • Carrying over 15kg now enables equipment rustling sounds accompanying your footsteps. And enables the backpack bodygroup.
  • Added SUPER MEDKIT

Heals 150hp with faster healrate. Regular medkit heals 50.

  • Introducing “medkit sacrificing”. You may sacrifice an unused medkit to increase your max health by 5hp. The maximum achievable overheal is 200hp, but be careful overdosing on nanocain leads to death.
  • Russian faction spawns with two vodka bottles, each healing 25hp. Charging sounds are replaced with drinking sounds.
  • Added variety of magazines for most weapons, including drum mags and c-mags.
  • New mechanic "encumbrance" momentarily increases your spread, scaled by the weight of your weapon and how fast you turn.( I.E. Handguns have low encumbrance while swinging around, while machineguns take longer to zero in after turning quickly. This accounts for swaying motions. )
  • Three types of shotgun ammo. Civilian Buckshot, Double-Ought buckshot and Shot ammo.
  • Civilian buckshot has only five pellets, While military buckshot has nine. Civilian buckshot will now be seen as red and double-ought as military green. Shot ammo is a single more powerful slug. Slugs are more accurate and will allow shotguns to play the sniping role. What will happen when somebody uses slugs in a fully automatic shotgun saiga-12 with drum mags!?!!11 1

- Modular Weapon Scripting.

  • No more duplicating weapon classes, this will decrease weapon code bloat a lot. We can easily support and add more weapons now.

- Improved Hud

  • Vector based panels. Borders will render properly on panels that resize dynamically. It's possible to use animated VTF for the background of these panels!
  • Better fonts that now read more clearly on most video resolutions.
  • Icons for PUMP-ACTION, indicating if the slide is in the forward or back state.
  • New font color code for brown ^&
  • New font effect ^s for shaking text. ( limit to 5 max for anti-trolling )
  • New font effect ^x randomized rapid color changing text "ACID TEXT"

- Vastly improved particle FX

  • More extreme muzzle flashes and more intense wall impacts - yet more optimized.
  • Energy weapons now leave glow sprites on impact
  • Russian thermobaric grenade fragments leave walls temporarily on fire.
  • Added support for "onbreak" spawning unique particle FX when props gib

- Casings are scaled by distance to the camera, to make them more noticeable further away. At all the close ranges the casings will be sized true for realism, while the camera zoomed out will have the casings scale up.

for a free game, this is one incredibly fun sci-fi creation, building on steam's co-op capabilities, which gives it immersive replay value, making it an awesome return-back platform for general cooperative-skills practice with new gamers and relaxing eye-hand coordination training gamers usually seek. given its free access to the game's sdk, enriches the experience even further, adding various creative production of new game content based on valve's source engine. what would u need more from a top-down…
