Short and sweet with solid mechanics that don't overstay their welcome. Location based damage, rock-paper-scissors style enemy attacks, Quake like visuals. While the price is a bit much, this is also a revival of a game that was barely known even in its own time. The remaster is done well with smooth movement, jumping, and added achievements that don't get in the way of the core gameplay. This is the type of remaster that should be encouraged. The original version is included as Dosbox as well for purists.
Great FPS in the vein of the classics. Solid amount of content, solid weapons with good feedback, and just the appropriate amount of carnage. The gameplay is fast paced enough so that it does not get stale, and keeps the focus entirely on gameplay rather than unskippable cutscenes. Too bad there's no multiplayer.
