The full Alpha 3 (0.10.150901) changelog:

* NEW: Traps!!! ( including many ways to detect and handle them as well as use them against enemies)

* NEW: "Special Map" (outside regular Complex 0b10, but not a normal branch)

* NEW: Any Signal Interpreter can identify where adjacent exits lead

* NEW: Overheating robots have a chance to be destroyed by critical meltdown each turn

* NEW: Heat from volleys now averaged over each of the duration's turns rather than front-loaded

* NEW: Some terminal hacks increase in difficulty with each previous success on same floor (notably Purge Threat)

* MOD: Slightly reduced patrol sizes in upper half of main complex

* MOD: Reduced ally effect on security level by halving threat modifier

* MOD: Moving clears all manual map labels

* MOD: Part rejection caused by system corruption no longer possible unless standing on an open space, and never rejects storage utilities

* MOD: Reduced rate of map data loss due to system corruption

* MOD: A portion of individual randomly placed items more likely to be of higher rating

* MOD: Lowered by 33% the threshold beyond which less agressive AI-controlled robots (e.g. Grunts, Sentries) stop firing due to overheating

* MOD: All non-light power source integrity +50%

* MOD: All tread integrity +100%

* MOD: All leg integrity +50%

* MOD: All machine explosion damage +50%

* MOD: AI patrols move in tighter groups

* FIX: Maneuvering Thrusters and Reaction Control Systems always dropped chance to be hit to 10% [Mando]

* FIX: Manual world seed wasn't properly applied when starting a fresh game (suicide-restart no longer required)

* FIX: Enemy move time miscalculation (slow enemies will be much easier to lose now, fast ones much more difficult)

Alpha 3 is here, and brings with it a completely new mechanic: Traps!  You won't find so many in the early game, but by the time you start making your way through the Factory they'll present an interesting challenge and can even become useful tools as well. Combined with the many balance tweaks and other changes, Alpha 3 will play somewhat differently than earlier versions.  Below I've highlighted what I believe to be the most important features you need to know about, but it's probably a good idea to skim the whole list, anywayFor a visual summary of a few of the new features, see here (As usual, if you haven't already, remember to use the form linked in your original download email to provide the name you want to use in game.  Attribution/names are added with each major release.):  This month we will be holding a major tournament.  You don't have to be the best (or even good) to win something, and there will be ongoing achievements and multiple leaderboards, so prepare for some semi-competitive fun.  Stay tuned for news on that.*  NEW: Auto-label system identifies discovered traps* NEW: Multiple trap-related terminal hacking commands* NEW: Maneuvering Thrusters give a chance to dodge triggered traps* NEW: Structural Scanners have a chance to detect traps within field of view* NEW: Allied Operators within 20 spaces of you identify hidden traps in your field of vision* NEW: Active melee Datajacks can be used to reprogram known traps (bump them, as with robot rewiring)* NEW: Hacking Suites and related (hacking strength) utilities provide a bonus to rewiring disrupted robots and reprogramming traps* NEW: Dynamic Insulation Systems can prevent the effects of shock/surge traps* NEW: Transmission Jammers block the signal sent out from alarm traps* NEW: Stasis Cancellers reduce or nullify the effect of stasis traps* NEW: Expanded manual with a new section about basic trap mechanics* NEW: Trap-related score records* NEW: 6 new robots (mostly confined to special new area for now)* NEW: 9 new weapons (mostly confined to special new area for now)* NEW: 2 new armor types* NEW: K-01 Serfs (Workers) in Factory dispose of disabled robots* NEW: Part rejection caused by system corruption blocks move commands for 500ms* NEW: Manual includes a section explaining "Advanced UI" display features* NEW: Press Left/Right keys to switch topics in manual* NEW: Enter/Up/Down keys all close context help window for stats* NEW: Double click/press same inventory sort button/key to reverse the sorting order* NEW: Options menu option descriptions also automatically shown in keyboard mode (on selection)* NEW: Save files have their own versioning system, meaning games-in-progress can be compatible with small/hotfix releases* NEW: Fabricators and Repair Stations play item drop sound effect when releasing items/containers* NEW: All supporter names registered since Alpha 2 added to in-game list (see Credits menu)* NEW: All item-attribution names registered since Alpha 2 added to the item collection gallery* MOD: "Enemies/Allies" buttons renamed to "Hostile/Friendly", now also label known traps* MOD: Direct "Local Emergency Access" terminal hack doesn't show unless there are applicable doors within range* MOD: Direct "Purge Threat" terminal hack doesn't show unless there are threat records to purge* MOD: Attempts to escape from a Stasis Beam take one full turn rather than basing on propulsion speed* MOD: Attempts to escape from a Stasis Beam no longer incur resource costs* MOD: Item labels for prototypes append rather than prepend rating asterisk, to match parts list info mode format* MOD: Cannot swap places with disabled/inactive allies* MOD: Manually seeded games always skip the tutorial map even if you haven't played it three times* MOD: Map object labels on cursor hover blocked when status window open (same behavior as item info window)* MOD: Map object labels on cursor hover no longer shown during attack animations* MOD: Entering targeting mode clears all visible map labels* MOD: Allied system corruptions split from general robot corruptions in score list* MOD: Replaced H-55 Commando's Hpw.
