Post news RSS HEMF - Major Update

Big patch which includes new enemy 'surges', doubles the enemy variety, reworks gear requisition/management, performance improvements, and streamlines gameplay!

Posted by on

The game is available at hemf.io for those interested, all in-browser. Haven't had too much external feedback, so if you give it a try, feedback would be welcomed and appreciated :)

New Content

  • 2 additional enemy toughness tiers have been added for each enemy type (4 x 4 enemy variations total now)
  • 'Surge' mechanic introduction; On a timer, a wave of varying composition, toughness, and volume will spawn in, emphasizing the need for special weaponry utilization and coordination.

Updated Gameplay Mechanics

  • Requisition is now more like a currency, where you buy an item and have that item until used (previously it was more of a loadout template, which could be refreshed)
  • Inventory management / buying and respawning all happen in the game world now to avoid loading out to a different screen, just to load back in.

Quality of Life Improvements

  • Item indicators have been added to the HUD's weapon status section to show which items are loaded as primary chamber, and underbarrel.
  • Buy menu reworked
  • Hotkeys are re-bindable with a right-click while in-game
  • Help text added for all hotkey groups (explain how the items work)

Engine Optimizations

  • RAM requirements significantly reduced (though due to new content, Chrome still uses at least 2gb)
  • Dead enemies are now 'instanced' to simplify their GPU overhead, which means performance won't dip as much as the operation goes on
