He is also very strong-willed and brave, although at times blurs the lines between courage and stubbornness. This is in part fueled by his intense love for Alice, making him willing to take on the seemingly invincible Dark Presence in the hope of saving her. Though it is unknown how he met Alice, it is quickly established that he cares for her deeply, and often refers to her as his 'muse'. During the Alan Wake DLC,The Signal, Alan has memories of Alice which seem to make him happy, most of which are sexual and intimate. Their marriage has recently become turbulent in some ways, due to Alan's insomnia and alcohol fueled behavioural issues, but overall the two love each other very deeply.

Alan also practices at a shooting range, and has a good knowledge of hunting rifles, shotguns, and pistols. In the novel, it is explained that he spent time at the shooting range to get research done for his Alex Casey crime series. Sarah Breaker comments that even though he is a good shot, he needs to get his knowledge of how guns function down. It should also be noted that he is a quick-thinker, using his knowledge to get past environmental puzzles and to evade numerous Taken at once.

Remedy Games has called Alan "kind of a dick." They note that, as before stated, he hates people, and has many problems with his marriage. But they say that this is good because it separates him from most golden-hearted characters and "space marine" G.I. Joes. This adds a layer of realism and depth to him, making him a more relatable character.
Taken directly from the Alan Wake Wikia.
