F1 – help, though it only shows default controls
F2 – to save, in some versions, may require patch for DOS
F12 – options from in-game
Controls felt super janky using a DOS copy, at least within DOSBox-X and the DOSBox settings recommended by PCGamingWiki. Holding SHIFT instead of turbo toggle was better but still much more stilted than I remember. GOG version had much smoother controls for me, though I suspect it’s not DOS-based. GOG version also had a few visual glitches like an outline around the screen and ammo sometimes doing a hall-of-mirrors trail outside the letterbox.
WADS and mouselook is possible, yet I had trouble with the DOS version. It seems the sniper mouselook is easily broken by changing too many bindings. What worked for me was carefully changing only the keys needed, using up-down arrows for looking up/down, and turning off mouse Y axis. Sadly the falling sequences end up worse, as on must use A+D for horizontal then up+down for vertical.
Also, mortar is accessible only from the “zoom” screen; which was very non-obvious to me. If there were analytics I would guess they’d say 40% of people got stuck there.
What did others think?
