Title screen - six entries instead of eleven: Play, Multiplayer, Research, Records, Settings and Exit Game. The modes live under Play, and the codex, leaderboards and achievements under Records.
Back returns to where you came from, so leaving the codex takes you back to Records and leaving a seed back to Play.
Scrolling lists - the codex, leaderboards, achievements, research and game lists stay where you left them when you select a tab or Back, and the mouse wheel scrolls the list or text under the pointer.
Daily Breach - one attempt a day, as a daily should be. The results take you straight to the day's leaderboard, and ending a run early still records your score.
The "CHOOSE A WEAPON OR UPGRADE" banner no longer shows up after you have already picked your loot.
Upgrades at their limit, and Reactive Shell with a full shield, are no longer offered as loot.
Survival - health, shield and ammo that nobody picks up now fade after 20 seconds, blinking first, so they can no longer pile up into an endless supply.
The codex text no longer scrolls past its last line, and file titles no longer run into their tags.
The Daily Breach retry button.
Bots can only be added before a game starts, from the lobby or the Play with Bots page.
