A custom card pack mod for ROUNDS featuring 60 cards themed around three brothers and their chaotic arsenal.
SWIP adds 60 cards across themed sets — each brother brings their own flavor of destruction, plus shared Brotherhood and Chaos Arsenal cards. Cards range from stat tweaks to full visual effects like poison clouds, laser beams, homing missiles, orbital strikes, and burn damage.
| Set | Creator | Cards | Flavor |
|---|---|---|---|
| Daniel's Cards | ASourFruit | 9 | Sour, acidic, poison clouds |
| Max's Cards | Synogence | 8 | Precision tech, lasers, drones |
| Sam's Cards | SaucyEnchiladas | 8 | Spice, fire, smoke, napalm |
| Brotherhood | Shared | 26 | Chaos, utility, gravity, terrain |
| Chaos Arsenal | Expansion | 9 | Burn, holy light, orbital, mythic |
Includes a custom Mythic rarity (magenta, 2% spawn rate) for The Final Boss card.
