Calculate the premium in your own currency

The US difference is $49.99 minus $39.99: $10, or about 25% above the base price. That percentage is a comparison of the two listed packages, not a discount.

Use the two prices shown in your own Steam store for the same calculation. Converting $39.99 with an exchange-rate calculator will not tell you the local store price. Check the final total before payment, especially if a price elsewhere comes from a different currency or an older promotion.

Which purchase solves your problem?

If your question is simply “How much do I need to pay to own WARDOGS?”, the base package is the relevant listing. The Supporter Edition is a bundle containing the game and a cosmetic pack. It is not a separate game subscription. EVIDENCE / 02WARDOGS Supporter Edition on SteamOpen source (opens in a new tab)

The Supporter Edition contents page covers the named items and what the package does not promise. Check that list before paying for an edition whose name alone tells you little about what you receive.

Buying earlier does not fix the unfinished parts

BULKHEAD says it plans a lower price during Early Access and may increase it as development progresses. The store does not give a final-release price or a dated schedule of increases. EVIDENCE / 01WARDOGS on SteamOpen source (opens in a new tab)

Our recommendation is to decide whether the current game is worth the current asking price. A possible later increase is a poor reason to buy if you are waiting for specific features or performance results. The Early Access overview separates that development period from the finished release, while the buy-or-wait assessment helps identify which evidence you still need.
