btw when it comes to gameplay, the multiplayer on the original Last of Us game was by far the most enjoyable tactical play Ive ever experienced. Shooters are not my preferred gameplay but that one really got me hooked because of all the custom tactical skill combinations. there was also the crates and crafting mechanic in it which added an interesting alternative focus to the strategies. A crypto like
LVL could be incorporated brilliantly in to a mechanic like this. For example, you could collect small amounts of LVL during the game if you focus on getting to certain sites at certain times, and if you decided to put your skill points in to LVL collection you might be able to harvest more, but of course that might disadvantage you in the actual matchup and therefore lead to less rewards if you perform badly.
other customizable skill combos in Last of Us multiplayer were things like:
stealth - skills that made you harder to see/hear/mark
physical - skills that made you stronger in melee , more resilient or faster movement/reloading
healing - skills that gave you advantages in healing yourself or your teammates (which reminds me, the WOUNDED status in Last of Us is absolute genius, where you are just crawling around bleeding out hoping for a teammate to heal you - this creates so many amazing moments in the game, i cant even tell you)
strategic skills - like improved exlosion radius, immunity to smoke stuns, superior marking ability, even meta stuff like being able to spawn near a specific ally after youve died.
there are many fascinating combos and Im sure this would be a mammoth development task, but I had to say something. If you haven't played the game, get Last of Us remastered on a ps4 or ps5 ASAP and get your chops around it. People are still totally addicted to it and it doesnt take long to find out why!
