Overview

About this game

Online Disclaimer

Classical Caliber Combat Contest has been developed with a client-authoritative network model. This means user inputs are instantly responsive and the experience will be smoother when players would normally experience issues with latency or lag. This decision was made by the Secret Handshake team after weighing multiple tradeoffs, choosing to prioritize game feel and groups of friends playing together over strict game security measures unfeasible for a small team.

Given that C4 is client-authoritative and contains public matchmaking options, Secret Handshake has taken steps to secure the online experience. This includes implementing community-driven moderation tools that integrate with both Quickplay and the Server Browser.

It is our intention to be honest about the challenges of publishing an online multiplayer game, and continue to provide solutions to these issues.

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

About the Game

Classical Caliber Combat Contest is the "Arena Shooter Party Game" where classic action meets Item Boxes, Random Crits, Stage Hazards, Minigame rounds, loads of Weapons, Modes and Modifiers, and the card-based Contest party mode!

Cards build the Match! Complete Missions to score Points, then cash them out for Gold in wild Minigames that happen during the action. When each round begins in the Lobby, select which card packs to open and level-up Cards. Build and play a strategic hand to attack and defend against other players, setting up the next match to the advantage of your selected Missions and play style. Don't get too comfortable at the top of the scoreboard, as a bit of bonus Gold at the awards ceremony might just swing the results!

  • Duplicate Cards combine and level up, making them harder to remove from the Board

  • Weapons gain lethal bonus stats and reactive Plus-Powers as cards levels up

  • Minigame events like the Gold Boss provide the opportunity to turn Points into Contest-winning Gold

  • Select from a variety of Missions that compliment your play style and influence your packs

  • Modifier Cards add stacking rules like "Infection" and "Floor is Lava" that flip the match on it's head

Construct your personal Arsenal from an enormous collection of weapons, including FPS classics and novel inventions. Alt-fire modes, bouncing projectiles and more make each weapon a distinct implement of mayhem. Will your favorite be the classic Rocket Launcher? Or do you prefer the crushing strength of the MEGA Shotgun?

  • Bullet weapons are well-rounded, like the adaptable Burst Rifle

  • Shell weapons are specialized, like the bouncing shotgun Slag Launcher

  • Voltage weapons are technical, like the precise Lightning Ray

  • Explosive weapons knockback targets, like the classic Rocket Launcher

  • Radiation weapons break the limits of power, like the questionable Bio-Blower

The Announcer narrates every point of action in the Arena, with more than 80 multi-kill, shutdown and special event medals to call and award. Battling across maps covered in dynamic stage hazards, a cast of computer-controlled characters fight alongside human players. With unique appearances, skill levels and chats, invite the strongest bots to your Contest if you dare!
