Strife: Quest for the Sigil is hybrid FPS game with complex storyline and RPG elements using Doom engine. It is developed by Rogue Entartainment and released by Velocity Incorporated in 1996. In this game we play as wandering mercenary looking for rebels to earn some money. I use GZDoom source port with remastered soundtrack. It is a first time that I play Elite difficulty, game is hard even on Rookie difficulty. Instead of fighting everyone I rather avoid unnecessary fights. I missed some thing because it would require to fight more enemies, and later in game it is hard to obtain ammo, armors and medkits (therefore earlier I chose Rookie difficulty). I think I've much improved my previous walkthrough (for example, I've found the way how to avoid fights in Oracle temple and Order's commons).
If you interested here is link to the remastered OST: https://www.moddb.com/games/strife-qu..., however it works only with ZDoom forks like GZDoom, Zandronum, Skulltag or ZDaemon. It does not work with vanilla Strife, Veteran Edition and Chocolate Strife forks.
