A fairly large expansion featuring five large-scale single-player maps and ten multiplayer maps, all made with high quality. Cooperative mode is available just as in the previous "Chronicles" installment.
Continuing the adventures of the security guard, this time he must carry out a mission in his own hometown.
The original gameplay of the first "Underground" returns in a modified form—quests can now be completed in co-op, and characters once again talk and argue with each other! The new addon will immerse players in the atmosphere of the first "Underground" installment. You'll play as the organization's head security guard, tasked with destroying a mass of negative energy that has been spawning alien invaders attempting to annihilate everything in their path. Quests are present on the final level of the expansion in a set of three. In co-op mode, players can look forward to highly original gameplay—groups can be formed to tackle missions simultaneously, with each group heading off to complete their own objective.
The main hero's voice acting stays true to previous "S.Z.R." addons—players will once again hear the hero's gruff mutterings and furious shouts, along with interesting and funny dialogues between characters.
This expansion introduces several new features, including: a time controller power-up (a time slowdown device), barrels that ignite before detonating with a delay (the barrel catches fire first and only explodes after a few seconds). Wooden crates can now be destroyed with a pistol after several shots, though a crowbar will still smash them in a single hit. Many new interactive objects have been added, such as new types of chests and cabinets. All the music was composed by the creator and fits the various locations and situations perfectly. Many game sounds have been replaced with more realistic ones—picking up different types of ammunition now produces distinct pickup sounds (similar to Serious Sam 2).
The gameplay is reminiscent of other works by ZombieZI: expect intense firefights against hordes of monsters, mission objectives, and scavenging items. Although all maps, just like in the previous "Chronicles" installment, are optimized for both single-player and co-op, this is already a completely different game—far more interesting and varied. For Deathmatch mode, ten maps are included. When installing the expansion, you can choose between English and Russian versions as well as several voice-over options. Scripted cutscenes (in-engine sequences) can now be skipped by pressing the "Use" or "Fire" buttons—though it's not recommended on a first playthrough, as you might get confused about missions or even miss your current objective entirely.
Models of headless enemies have been modified—they now have heads, and the kamikaze enemies have been redesigned to resemble their Serious Sam 2 counterparts. Textures for several models have also been reworked.
The game's locations are incredibly diverse: you'll explore a city, forests, basements, mountains, offices, warehouses, and many other interesting settings.
