It is a net loss in caps, because upgrading a merged room is cheaper than upgrading the individual rooms, but you will have your triple sized room at the end.

Theres lots of guide in Steam, and youTube, and some really good faq's to read. 1 Answer Sorted by: 12 Yes, it will merge with the other room once you upgrade it to the same tier. Just keep in mind, that internal vault events, like fires, radroaches, molerats & radscorpy's all ahve their event strength modified by the size and upgrade level of rooms they spawn in (as well as vault size and game mode, etc).

Also, if your first floor is a dead end, it forces raiders back through that 1st 3 wide room, fighting your very best dwellers twice in a row.Īfter that you can build as you like, asetics, purpose, etc. Originally posted by Maebus:Should I plan to merge all rooms into 3's or are some rooms not worth merging into 3? Your top floor, and maybe the 2nd floor should allways be 3 wides and 2 wides (don't upgrade all these rooms yet, not untill you have strong enough wpns & dwellers to defend the), for defence versus raiders that break down your vaults front gate and come charging in for loot and shennanigans.
