Wolfenstein 3D clone where you play as British special agent. Game is set in the future so the whole setting is sci-fi like. Level design is manageable. A few different type of enemies and 7 weapons to pick up. Plays ok I guess. You can look only horizontally, which is the main con here. Visual side is pixelated but good looking for such a game. Music and sounds are ok. Remember that game is from 1993 so don't expect much but for what it is it's a decent Wolfenstein 3D like shooter. Just make sure to grab source engine port which have many QOL improvements, like graphics scaling and mouse control that works good enough.

PS: Source port LINK [github.com]
Unzip and put it in the game folder.
Also I recommend to turn on BRZ x4 scaling in the options for higher resolution while still maintaining original visuals.
