Hi there,
thanks for your kind words, I'm here to help!
Combos
While it might seem random in some situations the combo on DOOM Pinball is actually reset by a simple timeout. Not every lane counts as a combo shot though, for example the skull won't add to your combo streak. Starting a mode or multiball will break your combo streak because they take time to happen. If you are really into combos, you can increase the default combo timer by using the combo perk.
Right ramp mini modes (aka Power Up)
Activating this mode will give you a power up to make it easier/more fun fighting demons. They all have a different effect on gameplay: Quad Damage will give you 4x damage AND 4x score, Invisibility hides you from the demons, Mega Health will boost your health and armor to the maximum, Invulnerability will make you.. well invulnerable, Berserk lets you destroy drop targets by one hit and the Demon Rune turns you into a Revenant for a short time. Feel free to experiment, a well timed Quad Damage can make your ok-ish run to your highest score
Trapped Ball 2-Ball
Shooting the captive ball enough times will add a new weapon to your arsenal. There are some special ones, like the super shotgun which starts a 2-ball multiball or the gauss cannon which will let you shoot the ball manually after a ball save.
Happy demon hunting!
