There’s a big update happening soon for Metal Slug Attack on iOS from SNK. More information about it can be located on the SNK site. While not my favorite F2P iOS game it can be a lot of fun. It’s pretty much a side-scrolling strategy game with a Metal Slug paint job. Surprisingly it’s been out for 5 years now. https://game.snk-corp.co.jp/official/metalslug_attack/news/20201230_01hs51x.html Just use Google Translate to read the above page in English.
