ЖДУ НОВУЮ ЧАСТЬ
I'm blown away. Instant fast action like in the good old times. Then variety and pacing like in the good new times. Quests, collectibles, modes of transport, minigames... so surprised you can even have all that while staying coherent and keeping the player engaged. Maybe I played too much trash the last couple of years, because I totally forgot you can have game design this good.
In my opinion, this is how Serious Sam 4 should have been.the gameplay ,in terms of the arena design is much more compact and action-packed compared to the original game, where there were just a bunch of empty spaces with nothing actually filling them up. The environment design is also very nice; it feels very Slavic. The only negative for me is that the game is so short, but since it's a DLC, that's understandable. It's a good Serious Sam experience, and the dialogue and characters are way better than in the original 4th game.

Every market we collect.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

The Show Must Go On
Тема огонь!!!!
lower enemy count so far than what i saw in serious sam 3 but tons of variety in encounters and creative secrets and easter eggs. each level is different and i'm always doing something new so far. i can see why some consider this the best serious sam game
