Continue with games recently played, that have roguelike tag on Steam:
Risk of Rain
So no turns, highly randomised, lvl, are randomly generated, items from chest/shrines are randomly generated and it's some chances for nothing. To get items you must pay with gold, which you get from monster or some conteiners on lvl.
Basically it's 2d shooter with some classes which have 4 different abilities.
Bosses fight are tough, for 90 second after begining fight with boss the monsters spawn near your location with increased rate, so if you stay in one place for long time you will see a sea of monsters.
The longer you play, the tougher the monster become.
To process to next lvl you must slaughter all monster on lvl, so probably better to go as fastly as possible to start boss fight, fastly kill monster, get some items and process to next lvl
Terrain can put you to high advantage.
Easier to play on gamepad, than keyboard

Game requires some agility and fast movement from player, for dodging monster attacks. Game don't require any sofisticating planning. Run to boss, kill mobs so they don't overrun you, process to next lvl repeat.
Could be quite fun to play on co-op

But this is not rogue-like. Or I have some hardcore definition of it. It give me quite similar feeling like Rogue Legacy, but change sword/magic to gun, and add mobs to boss fight.
