Compare Rule the Waves 3: Expanded Battles prices across trusted key stores and find the best deal. Developed by Naval Warfare Simulations. Published by Slitherine Ltd.. Released on 5/18/2023. Available on PC. Genres: Simulation, Strategy.

A tactical-combat add-on that does nothing without Rule the Waves 3 installed. For admirals who already fight their engagements by hand instead of autoresolving them.

Ultimate Admiral: Dreadnoughts fans know the pull of a tactical layer you can keep poking at, but this is not a standalone take on that. Expanded Battles requires Rule the Waves 3 to run, and it bolts onto that game's tactical combat rather than its campaign and shipbuilding side. What it does is widen the battle end of the sim, adding more ways to set up and fight engagements outside the normal campaign flow. The data here does not itemise every scenario, so read the store listing for the exact breakdown before you commit. Aimed squarely at players already deep in RtW3 who fight manually. If you autoresolve and stay on the arms race, skip it. Diego, Scout Team

GamerScout Verdict

Only for RtW3 owners who fight battles manually; needs the base game and touches the tactical layer alone.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
