The current test module of Crowfall, Siege Perilous, is all about taking on a keep’s defenses and taking control. In theory, anyhow; in practice the point of the battle is, well, testing the battle. You’re not really taking control of anything in the longer term. But the next test incarnation, Throne War, will see you tying the game’s combat and sieges together into a small version of how the game will play out in the end.
Throne War is something of a mini-campaign, much smaller than an actual campaign and with far fewer moving pieces. Players will still be able to capture resources, hold keeps, defend them, take control of them, and so forth. It won’t be everything offered by the game in the long term, but it should give fans eagerly awaiting more of the core game a preview of how things will play out in longer conflicts. The test’s “campaign” period is planned to last for around half a week. It’s still a ways off, but that alone should be enough to get players excited about the prospect of the next stage in testing.
