Steredenn is a classic “shoot 'em up” scrolling shooter, spiced up with random generation and roguelike mechanics. You should not expect a clear plot – what is happening is aimed only at flying the screens from left to right to the boss and destroying him. On the way you will encounter weaker opponents, as well as various obstacles and events. All of them, along with the background and decorations, are generated randomly each time. In addition, according to tradition, after death, all progress is reset.

Steredenn has 4 game modes:

• Single player campaign. It asks you to go through 7 locations and bosses in a row to complete the passage.
• Cooperative. Similar to the single-player campaign, only you fly with friends in local mode. There can be up to 4 players in total.
• Daily runs. A game for the highest score among the leaderboard, where all participants have the same in-game conditions.
• Arena. The opportunity to fight each of their bosses in a new way, but with customizable conditions.

You will have to destroy opponents on one of 5 spaceships. Each of them has slightly different characteristics and skills. However, the ships are identical in their ability to mount various weapons, of which there are 42 to choose from. Among them are the usual missiles and lasers, as well as huge steel jaws, drones, flamethrowers and other unusual weapons. Those from special opponents at levels drop out. You are allowed to carry up to 2 guns on board at a time. In addition, there are 30 upgrades to skills and characteristics acquired as you progress.
