How to Play Duke Nukem: Critical Mass
Quick start
Start the opening stage and practice moving, jumping and the first required action. Clear one obstacle at a time, watch enemy movement and learn a safe route before returning for collectibles. Check the stage goal when a path seems blocked.
Controls
Use the DS directional controls to move and the shown action buttons to jump or perform the current character's move. Read the tutorial when a special obstacle appears and use the pause or selection menu for the options it offers. Time inputs around the scenery rather than tapping the touch screen as a universal action.
Duke Nukem: Critical Mass — About this game
Critical Mass on DS combines side-view run-and-gun stages with sections that change the action's viewpoint. Fight hostile creatures, cross gaps and manage the distance between Duke and the next threat. A weapon that clears a corridor still requires careful timing around an exposed ledge or an enemy firing from another height. Learn the opening stage's movement before spending health on a rushed attack. When the presentation changes, read that section's aiming or movement instructions rather than carrying over a PC shooter layout. Begin with the opening tutorial and practice the main interaction before pursuing optional rewards. Read the current objective, make one deliberate choice and watch its effect before repeating it. A short first session makes it easier to separate a missed instruction from a difficult challenge. Return to the available menu when you need to check progress or adjust your approach, then continue from the next clear objective.
