An enjoyable RTS / Tower Defense / RPG hybrid with roguelike elements that will sink in your head for days. The gameplay is original, yet extremely challenging even on the lowest difficulty, the art-style is gorgeous and minimalistic, and there is tons of content just thrown at you at every turn. It's also story-lite so there's no walls of text thrown at you constantly.
The game has a steep enough learning curve, only giving you a short tutorial on the basics, requiring you to figure out things for yourself.
You start with two heroes, but eventually you will unlock up to two more hero slots as you find them in the dungeon, with a total of 16 different heroes available to choose from. Resource managing is key in Dungeon of the Endless.
If you want strong characters, you'll need to build food modules,
if you want tons of laser cannons to stop wave upon wave of enemies, you will need machinary resources.
And if you want access to additional modules ranging from decoys, lasers, bombs, then you'll need to gather science resources.
(Here is the part where I explain how to play this game, making it even more confusing.)
The game has a unique "turn" system, designated by a door, i.e. when you open a door, a turn will pass, giving you resources based on modules you have built. Anything can happen during these turns. A wave of monsters can surprise you, power can go out, you may uncover a buff crystal or a research post, or a shop where you can spend a specific randomly chosen resource on some neat stuff.
The objective of the game is to find the exit in the dungeon, allocate a hero to carry the crystal at the start of the level, and escort them to the exit, while of course, being bombarded by enemy waves.
Rooms can be lit up using "Dust", the primary resource in the game. It's collected from enemies and certain rooms when opened. Dust is also the crystal's health, so if attacked, you will lose dust, thus losing power in rooms.
Lighting up the rooms stops enemies from spawning during turns and the "final" phase, but also allows you to place modules on the dungeon floor at the cost of machinery resource.
The game is perma-death, so if your crystal is destroyed, if your heroes die, or if the hero carrying the crystal dies, then it's game over, and back to level 1 again. There is a number of different "pods" you can choose from, all with various difficulties and requirements, so there is plenty to mess around with here.
There is so much more to this game, including levelling up your heroes, learning new skills, abilities, picking up or buying/selling items, weapons, armour and accessories, triggering random events and most importantly, taking a whole bunch of risks.
It's one of the most perplexing and gripping games I've played in a long time and you should buy it when you can.
(There is multiplayer, however I haven't got around to taking a stab at it yet, but when I do, I'll update this review.)
