What if there was a reward for "100%ing" the game (such as an exclusive cosmetic, a substantial amount of carl coins or saw tickets, etc.) that was given after completing most of the base objectives this game has to offer? This could serve as an incentive for players to fulfill certain aspects of the game and to complete the milestones/objectives that many players avoid completing.
Some examples of these objectives could be:
- Unlocking all base animals
- Completing all Milestones (including unlocking all white gun skins)
- Reaching a certain level (300, 500, 1000, etc.)
- Completing at least one Animal Pass (no need to purchase it)
- Completing all achievements (i'm not sure if the other platforms support achievements or if it's just Steam)
