Well, not my best game about FPS genre (I mean often play those FPS genre) but when this one have this mod so... I won't sit tight to grab and play it. :) This game is similar from Twilight Escape From Stalliongrad, but mana (actually is ammo) it different use then that one because it have category ammo type

I'll tell all 4 mana color at once (if I didn't know those much sorry about that)

Red mana type use on Simple Spark (fire like Pistol) and Rapid Spark (fire like Rifle or SMG) those 2 not useful much to shot those Changeling have high HP except it good at long distance and some Changeling have low HP

Blue mana type use those Spread shot, but it have 3 Level in this one, when you found that first Level 1 Spread shot, after shot it will spread little magic from fire and cost one mana, Double Spread shot (Level 2 Spread shot) when shot it will have more spread then Level 1 Spread shot best to shot them on close distance and cost 2 mana. Last one Nightmare Spark, (Level 3 Spread shot) this one unlike Level 1 and 2 because need to find those 3 spell pieces for this Nightmare Spark, this one it really powerful to group kill at close distance or nearly and cost 3 mana, but Nightmare Spark can't hold Left click on Mouse (default is Left Ctrl in Keyboard but option key I set is use Left click on Mouse) this one it required spam Left Ctrl in Keyboard or click on Mouse and not recommend to use in some those Changeling have little HP in single group, because it waste mana to safe for use in next map

Purple mana type use for Twilight Concussive Blast (it RPG) this is really useful in group and deal massive Damage then Spread shot Level 1 and 2, but mana pickup about small one can gain only 1 mana and big one can gain 5 mana, this spell it required to use when on emergency if player get stuck by Changeling when they block your way, use this spell for manage to escape freely, and about Alt-Fire I won't recommend to use it because it same Damage from you Fire primary one, I know it cost 2 mana but Damage it same amount deal at them

Orange mana type is use those Flamethrower and Epic Thrower, about Flamethrower is fire like Chaingun except projectile is different useful for stop incoming attack from those Changeling shot projectile, Epic Thrower I'm not sure about shot what it look like from those gun, but it useful for deal those massive group of Changeling and deal high massive Damage then Nightmare Spark and RPG, problem kinda waste mana because it cost 40 mana per shot, this one use wisely to clean up them

Some info
This Raridoom Beta 3 is release around 2015 or 2016, actually it have Beta 4 but about Episode it not exist unlike on Beta 3, sugarcube. And if someone see in Mirror in Episode 2 Map 4 and Episode 3 Map 6 what is those mean? That Mirror it secret map, sugarcube. I decide ignore that one because it not important thing for me, :P and I know it help to skip Map but I don't like to skip it, sugarcube. :) And if y'all see why my aim it good, because I played this game 23 times to warm up and memorize those path, what path can go and some secret to help some gain mana or HP and Armor. :) Those HP and Armor it different max amount, HP is max 400 and Armor is max 200, when HP is reach 200 if you go to pick Daisy can't gain more to HP 201, until pick Apple Juice for gain further to reach Max HP 400. Next, if someone see why I use Melee sometime to kill them? Well, because I'll safe some mana to kill what Changeling it high HP instead, sugarcube. :) Like Episode 3 after start this Episode those mana it really hard to find. Last this Longplay I play difficult There Will Be Blood (Insane difficult) but why I play this difficult? Because it easy then Twilight Escape From Stalliongrad and not use same ammo category like that, sugarcube. :P And when play this difficult projectile from Changeling will faster and more Changeling amount then Easy, Normal and Hard difficult. Well, if y'all wonder why I won't play Episode 4? Umm, hard to tell because when I choice Episode 4 True, True Friend it said Episode 4 Map 1 is missing, this problem why I choice Quit Game instantly, sugarcube :(

Other more when I search in Youtube to find someone did already record and upload Longplay video but no one do this one. So, I decide to do it and play in one sit, sugarcube. :) Well honestly, this game it not long played time then other, that why I can play this game in one sit. :) Anyway, hope y'all enjoy this Longplay :)
