Some free coop game for bad pc

[Cuttyflame]

My friend and i are searching for good coop games. I wouldn't mind if i would have to pay but the problem is, my friend is a little bit difficult. I already bought him 3-4 games but he ended up disliking them and refunding them in 1 hour or less so yeah free is the best choice to see if he like them

1. He liked dust 2 until the remake so no more csgo but shooter is still an option

2. He doesn't like horror so no killing floor (lol) (1 copy from a bundle wasted)

3. He kinda like paladins (except the p2w card part) and surprisingly is willing to buy overwatch on sale (the only game he want to buy though)

4. He like pvping in minecraft yet this is the only thing i hate

5. He didn't like trove that much though

6. He has a bad pc so he cannot run games like warframe or fortnite (that's the only 2 game he tried that i remember)

For me, i like almost every game, except the one where you need hour of practice to be good at (minecraft pvping)

Thats pretty much every info i have right now so thanks in advance for your recommendation.

Terraria works on a pretty basic computer. I remember it running in 800x600 windowed on an old Pentium computer a few years ago.
