Performance Fixes, New Weapons + Modes in the C4 Multiplayer Demo v2.0!

Classical Caliber Combat Contest Soundtrack · published 16 Oct 2025, 21:30 UTC

All eventsPlayers around this dateRead on Steam

The C4 Multiplayer Demo has been updated to version b28_2.0! This update includes new trial weapons, a game mode, multiple Modifiers, performance fixes, and general game improvements.

Content

  • Weapon: Burst Rifle

    • This Bullet weapon demands precision with it's three-round burst and high headshot multiplier, but can deal large amounts of damage if kept on target.

  • Weapon: Incinerator

    • This flamethrower-type weapon burns Shell ammo to unleash a barrage of short range fire blasts. What this weapon lacks in range it makes up for with high damage and a powerful alt-fire mode that can blast targets back.

  • Weapon: Ray Gun

    • This lightweight Voltage weapon fires projectiles that take skill to land with precision, but reward accuracy with high damage.

  • Weapon: Mortar

    • This Explosive weapon lobs fast-moving projectiles with high gravity in an arc. Projectiles increase in impact damage as they travel and deal increased area-of-effect damage on impact, so go for the long shot!

  • Weapon: Fissile Collider

    • This Radiation-fueled auto shotgun shreds targets at close range, and has an alt-fire projectile that can pull targets in to the weapon's range of engagement.

  • Game Mode: Capture the Flag

  • Modifier: Juggernaut (+ a few more!)

    • The Juggernaut Gear will appear at a random location shortly after the match begins. Collect the pickup to don the powerful Juggernaut Suit, complete with it's own theme tune! Defeat the Juggernaut to claim the gear for yourself, inheriting whatever time they had left.

Performance

Thank you to the players who took the time to report the performance issues with the Demo! We took these reports seriously as soon as we received them and got right to work patching some big issues with frame rate averages and spikes. In this update we are making multiple changes to optimize player and weapon models, the user interface and HUD, and NPC bots.

We have also added a graphic to the Host Server screen that illustrates the performance impact of adding bots to your game. We recommend 5 bots on a mid-range PC. Setting the Bot Fill target to 6 (the default) will make sure you either meet or come in under this number. We aren't going to restrict the number of bots you can add, but we thought it was wise to let you know that running that many virtual brains is not free.

Version b28_2.0 also includes fixes made to the Demo in the first three days. Thanks to our community for reporting these issues on the Discord!

  • Demo Missions progression blockers

  • Issues with the Contest Mode finale sequence

  • Problems with sounds not playing or finishing too late

  • Concerns with UI flow and user experience

Thank you for playing the C4 Demo!

Secret Handshake Interactive is brought to you by players like you.

Thank you.
