8 Best Roguelikes That Are Best Played On A Steam Deck
These excellent Roguelikes not only play wonderfully on the Steam Deck, but they truly shine in the grab-and-go handheld format.
One of the main mechanics that the game has for meta-progression is Perks. When playing with a specific King, players level up that King when the run is over, giving them perk points that they can spend on the available perks for that particular King. The King of Nothing, like his peers, has nine kings that players can invest in.
9 Persistent
Browse the World for Free
- Receive 2 free re-rolls per rank.
- Three ranks
The Persistent perk should be the lowest priority for the player, all things considered. There’s nothing bad about getting 2 free re-rolls per rank, but it’s just not as good as the other options that King of Nothing has available.
Rerolls can be used to get new options in the shop, for card rewards at the end of each year, and for royal decrees.
That being said, there are three ranks to the perk, meaning players can get a total of 6 free rerolls. This can give them a great way to hunt for specific cards when creating a build, especially in the shop.
8 Lucky
The Colors of the Rainbow
- Special cards are 10% more likely to appear in shops per rank
- Two ranks
Special cards are rainbow colored cards that appear every so often in the shop. They cost the same as normal cards and have unique powers that aren’t beholden to any specific King. They can be quite powerful in the right circumstances, but it all depends on the player's build.
8 Best Roguelike Games Of The 2020s, Ranked (So Far)
The 2020s era has released some iconic titles of the roguelike genre, and these are the most outstanding.
Increasing the chance of these cards appearing in the shop isn’t necessarily a good or bad thing, but at 20%, this perk gives any player who wants to get more special cards a decent chance at getting their wish fulfilled.
7 Ingenious
A Warrior King
- Your castle can now level up 3 more times per rank
- Two ranks
Leveling up plots is a very important mechanic in the game that forms the basis of the player’s build. Getting level three cards on the board early on means that players know what build they want going forward, giving them the direction they need to make a formidable fighting force. With four kings on the board, the chances of the player getting the card they want are 1 in 36.
Additionally, those numbers drop down even further when considering that cards only appear when fighting the kings they belong to, i.e., the cards for the King of Nothing won’t appear when fighting the King of Blood. The Castle is a card that can appear in any battle and can be consistently and easily upgraded. Having a way to increase its level past the normal barrier is quite useful, especially in situations where the player doesn’t have an immediate plan for the future.
6 Planner
Something To Bounce Back
- Losing a life gives you +30 gold per rank
- Three ranks
In the higher difficulties of 9 Kings, when small mistakes compound and every year of lost ground means a future year full of suffering, having a small boost from losing a life can be invaluable.
When fully realized, this perk gives the player 90 gold per life lost, giving them a lot more flexibility when they’re in dire straits about what they can or should do. It’s a lifeline that can help the player rise from their ashes, better than ever.
5 Nurturer
Realm of Tanks
- All troops start with +10% HP per rank
- Three ranks
High-health troops are nothing to scoff at. They form the frontline in battle and draw the aggro from most enemies to spare the less health-blessed troops behind them, letting the others deal damage while they bear the burden of enemy fire.
14 Best Roguelike Games On The PS5, Ranked
PlayStation 5 players looking to dive into the world of roguelikes have several fantastic options to pick from on the console. Here are the best.
The perk gives a flat 30% HP increase to all troops, giving everything a little extra wiggle room and making the player’s tanks that much better at their jobs. It’s not going to change the outcome of a losing battle, but it will help any builds that rely on high-health troops quite a lot.
4 Hoarder
More Options Are Never Bad
- Start with +1 random card from your king in hand per rank
- Two ranks
The start of a run in 9 Kings sees the player putting down their starting tower, and then getting a hand of 3 cards they can use as a starting off point. Having an extra card at the start can be quite valuable for players who are looking for a specific build.
Two ranks in the perk means that players will start with 5 cards in their hands, almost double the normal amount. This makes the perk well worth it. It also lets players put down the extra card, so that the battle starts when they place or use two cards, not one.
3 Expansionist
More Real Estate
- Start with +1 random unlocked plot per rank
- Three ranks
Land is the most precious resource in the game, and it is very difficult to get in normal situations. Players get the opportunity to unlock land once every few years, getting no more than three or four extra plots if they’re lucky.
Best Roguelike Games For Fast-Paced Gameplay, Ranked
For roguelike players who like things fast and frenetic, these games will be a perfect fit.
The Expansionist perk gives the player 3 plots from the get-go, making it a must-have for players who want to have more freedom when playing the game. It is worth saying that these three plots are random and may not be as powerful as three plots that the player handpicks.
2 Politician
Say What You Mean
- +1 royal decree option per rank
- Two ranks
Royal Decrees are powerful buffs that the player can avail once every few years in the game during Royal Decree events. There is a special card in the game that can trigger a royal decree event, but it requires the sacrifice of a plot.
The Politician perk gives the player two extra options to choose from when a royal decree event occurs. Normally, there are three decrees that the player can choose from, but with five decrees, getting the one that the player needs in any given situation is much more likely, especially with a few rerolls.
1 Fortifier
Focus on Construction
- Towers deal 10% more damage per rank
- Two ranks
There are two ways to deal damage in 9 Kings: Towers and Troops. Towers are often overlooked compared to troops because of their lower profile during battles, but they can be equally as important, if not more important, than the troops on the ground.
20% extra damage is nothing to scoff at, and with the high damage output that towers can achieve, the percentage increase can go a long way.
