About C4: Supporter Pack

C4: Supporter Pack - about the game

C4: Classical Caliber Combat Contest is an action FPS arena shooter party game that blends fast-paced classic combat with layered party mechanics on PC. Players compete in arenas using a wide arsenal while strategic card play shapes each match through missions, modifiers, and minigames.

Gameplay

The core loop centers on arena-style movement and shooting across maps filled with pickups, stage hazards, and interactive elements. Weapons spawn on timers, and each player selects from five ammo slots that determine available options during a round. Combat features punchy feedback, random crits, and comeback mechanics through item boxes that reward positioning and survival. A fully voiced announcer tracks performance with over 80 medals for kills, streaks, and objectives.

Twelve distinct NPC bots join matches with varying skill levels, unique appearances, and chat lines that react to events. These bots navigate arenas, collect items, and engage targets in ways that mimic human opponents. Stage hazards such as death pits and grinders add risk and tactical depth, allowing skilled players to knock foes into instant-kill zones.

Impactful items expand options beyond standard firearms. Examples include the grapple hook for mobility, sensors for tracking, auto-missiles for area denial, and pickup portals for repositioning resources. These tools integrate into the flow of combat without replacing core shooting skills.

Game Modes

Free Play supports fully custom matches with adjustable rules, team sizes from free-for-all to four-player squads, and replayable setups. Party mode emphasizes the card system for structured yet varied sessions. Fan-favorite options include Deathmatch for pure elimination, Capture the Flag for objective-based teamwork, King of the Hill for control-point dominance, and Zone Control for area management.

Each mode accommodates 2 to 12 players across eight maps, with four layouts per map to scale for different group sizes. Modifiers stack to alter rules dramatically, such as Infection for spreading effects or Floor is Lava for environmental pressure. Up to 24 such modifiers exist, creating fresh combinations every session.

Card-Based Contest System

The signature Contest party mode uses cards to build matches dynamically. Players complete missions to earn points, then convert them into gold during in-match minigames. In the lobby between rounds, participants open card packs, level up selections, and play hands that influence weapon stats, add plus-powers, or introduce stacking modifiers.

Duplicate cards combine for stronger effects, while modifier cards flip match conditions. Easy, medium, and hard missions cater to different strategies. This system encourages adaptation and long-term planning without removing the immediate demands of arena combat.

Is It Worth Playing?

The game targets fans of arena shooters who enjoy added layers of strategy and chaos through cards, modifiers, and minigames. Its mix of old-school weapon handling with modern party elements creates repeatable sessions that shift based on card choices and group composition. Bots provide reliable opponents for solo or small-group play, while the announcer and medal system reward skillful moments.

Development continues with regular updates adding weapons, maps, modes, and refinements to the card economy. The title remains in active testing ahead of its 2026 release, with a focus on player-driven support. Those who appreciate customizable matches and evolving rulesets will find consistent depth here.

Supporter options exist for players who want to back the studio directly. These contributions help sustain ongoing work on the core experience.
