This game should have clearer rewards for what constitutes as winning. There are tiers to winning and losing. Wins should be clearly ranked as bronze, silver, and gold.
Finishing the mission and at least one person escaping is a bronze win, causing the predator to self destruct is a silver win, capturing a predator body is a gold win and should be rare.
Getting at least one quick claim is a bronze win for the predator, getting at least one long claim is a silver win, and wiping the team or getting at least one claim in addition to preventing any fireteam escapes are both gold tier wins and should be rare.
The game should be balanced around these outcomes and the rewards should be listed on a stat page, or the best option for predator fans would be a trophy room.
