Btw: There are USB foot keyboards on the soulless online marketing platform of your choice. They can usually be programmed to different keys or combinations. While it is not something I would use for FPS gaming, it can come handy in situations like yours. I have one with three different switches that are programmable which is quite handy.
Definitely not the best, but still worth a mention is “Stormworks: Build and rescue”. Basically a Lego like “build a ship/plane and do missions on the oceans” game - missions nowadays are also including far more than rescue.
