If none of the title made sense to you, I’ll break it down:
- Gabraltar is Pokémon speedrunner who also makes videos on the GSC metagame
- Co-op Diploma is a speedrun category where you play three games simultaneously and try to catch ’em all and obtain the diploma in each.
- TAS stands for tool-assisted speedrun, meaning this run was done using a bot or program
What’s more, Gabraltar annotated their run so you can see what’s happening and why.
