A PiDP would be a great prize for the weirdestoldestretroest submission to a ' retro edition challenge '. Oscar ' s working on the PiDP 1170 , which would make for a great prize . As far as Supplyframe getting stock on the PiDP , that ' s . weird . We also have Tindie , which is doing gangbusters , and leaving the official Hackaday Store in the dust . We don ' t do fulfillment for Tindie only the Hackaday Store and this is starting to make things weird . Either way , you ' re right . A PiDP would be a great prize for the most retro access of the hackaday retro edition . <| sep |> Looked into it and clearance is actually lower on Q 5 . Thanks for the extended reply . <| sep |> So right now its $ 19 . 99 on Steam for the deluxe edition or $ 15 for the regular version . I ' d say its easily worth it . A lot of the content you can enjoy solo particularly the Story Mode campaign . Each map is kind of like a dungeon in an MMO or Borderlands for that matter . They are packed full enemies , feature 2 boss fights , and several objectives you have to complete escorts , defend points , etc . . While there may be only 8 of these in the original story mode the $ 15 version , the maps aren ' t 100 % the same from play through to play through . Dialogue changes , location of bonuses can change , and the bonus objectives can change . On top of that , you can add in an advanced difficulty , and a hardcore mode if you want to make it even more challenging . The game also keeps track of your best time , and best score , so you can replay the maps and try and do better . As you run through these maps you get gear , unlock additional characters , and unlock additional mutations talents for your characters , character lore , or titles . The $ 19 deluxe addition includes operations which are like two additional story mode maps with 3 more on the way . These don ' t have variable difficulty settings no advanced difficulty . Instead , they have OPs points which you go around collecting or completing objectives to get better loot skins , or loot packs while at the same time gradually increasing the difficulty of the map . If you do well additional play through start with more OPs points meaning the play through is more difficult and potentially more rewarding . In addition these Operations include different story ' s each time you play them 10 different ones I think making them fun to play through multiple times . There is a pretty diverse range of characters in the game , and they can play radically different from each other , and in addition the in game mutations , or loot you activate can even make the same character play a little different . All the stuff I pointed out above you play solo whether or not there is an active player base . Both story mode and OPs can be played in CoOP and the game will adjust the difficulty accordingly . Last , but not least there is a PVP mode which plays more like a MOBA combined with an FPS . It can be really fun once you get the hang of it .
