Five Plus TwoBad Traffic0.7%A timed Reliquary challenge. Loading Domination from level select with it gives you only a pistol, and dying sends you back to the checkpoint with the full minute again (player report).

Hand of GodZeus Juice0.4%A gold-tier modifier. A player who unlocked 'god mode and manus dei' could not run them together, which matches the one-gold-modifier rule; Manus Dei is Latin for Hand of God, but the game's own label is unconfirmed.
God Mode5>00.4%A gold-tier modifier; cannot be combined with another gold modifier.

Relic tiers

Still unknown

MAETH has not published a modifier list, so most effects above are marked "not documented" instead of guessed from the names. The total number of Relic Fragments is also unconfirmed: Worth A Buy estimated "about 80" before finishing the game, and one player counted three relics in Buried. This table will be updated as patch notes and player reports come in.

Modifier questions

How do you unlock modifiers?

With Relic Fragments, the collectible hidden in every level. After you beat the campaign they are spent on modifiers and on level challenges. Each modifier has its own Steam achievement.

Can you use more than one modifier?

Only one gold modifier can be active at a time. A player who unlocked God Mode and a second gold modifier reported it, and the answer on the Discord was that this is intended. Players have asked MAETH to allow stacking.

Do modifiers make the game easier or harder?

Both, and reviewers disagree on the balance. Flexin85 says the relic perks all make the game harder; Worth A Buy expected "some really good things". The Rusted Relic achievement is called Masochist and the gold ones include God Mode, which suggests one tier handicaps you and the other helps.
