The basic in-game currency you use to buy Mechs resets to 0 at the end of every season.
(You can check the description by hovering your cursor over it in the upper right)

If you do not purchase the Mech you're saving for by the end of the season, your progress is therefore wiped.
You can not save up for upcoming Mechs.

If you're a casual player, you will not have fun with this feature.

Good.

I have not played much Nebulous yet, as I'm waiting for the campaign mode.
However I am leaving a review to counter some of the negative reviews on this game.

There are several reviews (around June 1st, 2024) stating that the campaign mode for the game has been canceled or abandoned.

However, on April 14th, 2025 the developer put out a devblog showing the ongoing development of the campaign, which has undergone extensive redevelopment.

If you are interested in the game for its setting and systems, and looking forward to a future PvE campaign (with co-op support!), I highly suggest picking up the game to help support the developer!

This is the real-life equivalent of the skyrim time skip menu.
Enjoy at your own risk.

I highly suggest disregarding a lot of the negative launch comments on here, as the game is pretty damn good for its price.
If you're looking for a simple sidescrolling roguelike, and some characters with more extensive movesets than what you would get in most games, this one is fantastic.
The game definitely needs more content, but the core of a great game is here and is already pretty fun.

Got about 10 hours of playtime out of it, still have another run to do at at least three more items to get.

I enjoyed it immensely. The atmosphere is top tier, the level design and zone progression is handled in a refreshing way compared to standard Remnant II content, and the equipment and class is enjoyable to play with.

More Remnant is more Remnant.

Only requires one player to have the DLC to access the new area.

This is a fantastic multiplayer game, and it thrives, lives and dies on being able to play it with friends. Thank you for listening to player feedback.
