Terraria Cards

A collection of Terraria-inspired weapon and ammunition cards for ROUNDS, featuring custom weapons, colourful visual effects, and unique combat mechanics.

Cards

Weapons

• Terra Blade — A powerful green energy blade with a custom projectile slash effect.
• Minishark — A rapid-fire weapon inspired by Terraria's iconic minigun.
• Megashark — An upgraded rapid-fire weapon for even greater firepower.
• Last Prism — A continuously firing rainbow laser that charges into a powerful concentrated beam, featuring reflections, custom visual effects, and magical audio.

Ammunition

• Meteor Shot — Special ammunition inspired by Terraria's Meteor Shot.
• Crystal Bullets — Crystal-themed ammunition with additional projectile effects.
• Cursed Bullets — Inflict Cursed Inferno, featuring a custom green flame effect and damage over time.

Early Multiplayer Testing — v0.1.1

This is an experimental multiplayer testing release.

Recent development includes:

• Additional Terraria-inspired ammunition cards.
• Improvements to Cursed Inferno's green flame visuals.
• Continued refinement of Last Prism's visual effects, charging animation, and audio.
• Initial multiplayer compatibility testing.

Known issue: Last Prism's laser visuals may not appear for other players, even when damage is being dealt successfully. Multiplayer visual synchronisation is currently under investigation.

Other card interactions, performance, and network behaviour may still require additional testing.

Installation

Install through Thunderstore Mod Manager / r2modman for ROUNDS.

Required dependencies should be specified in the package manifest.
