Final prices with fees and discounts applied
Relic Guardian Tower Defense for PC starts at €6.00 (€6.62 with fees) at Driffle, a Steam key, which is 66% under the €19.50 (no fees) it costs on the official store.
That €6.00 (€6.62 with fees) already includes the GOCDKEYS10 coupon, so apply it at checkout or the store will show you a higher price.
With 14 offers across 11 stores there is enough competition for the price to move, so the gap between the cheapest and the rest is worth checking before you buy.
That puts it 22% under its average of €8.59 since 2025, so today is a better entry point than most days of its life.
That €6.00 (€6.62 with fees) key is at one of its best prices.
