Might take a couple of Days for me to add all the Categories so here is the starting ideas for each Category and the rules. (They might change slightly)
So since this game is mainly Online we have to be creative with the Speedruns with this game. Luckily there is an Private Match Option where you can play Solo as the Predator or the Soldiers and fight against the AI.
Private Match "Predator" - The Predator cant actually "Win" in this mode so the Speedruns for him will involve Killing AI as fast as possible. Killing 5, 10 and 20 AI as fast as possible. For this Category we will use Real Time (igt isnt viable) and the timer for the run will end right as you get ur 5th, 10th, or 20th kill and the xp for the kill pops up. After the Kill you need to show proof of the last kill by showing the menu with your total AI kills.
Private Match "Soldier" - As the Soldier their will be no Predator to face off so the Speedrun will just be doing all the Main Objectives and getting back on the Chopper as fast as possible. This will also use in real time to time the runs. Timer ends after inputting button to enter the chopper.
Their are 3 different maps to choose from so both Predator and Soldier Runs will be split into 3 categories (1 for each Map) and their will be an option for Coop runs for the Soldiers team (up to 4 players).
One other Speedrun category will be the Predator Tutorial. Its basically little obstacle course to hop around and master the movement of the Predator.
I will be looking into other Possible Categories but as of now this is all that can really be done with this game. Hopefully they add more Offline functionality to this game in the future.
