 their enemies, distinct bosses, weapons and original soundtrack automatically,

 be enabled individually; each mission selects its own dependencies.
+**Lightning Cannon** and **Lightning Shield** are two additional independent
+weapon mods. Enable them in Mods and buy them in the supply room. The cannon
+is a selected special that chains through nearby targets; the shield fires
+with your primary guns while Fire is held. Both ship SD/HD icons and sounds.
 For a user mods folder, pass `--mods DIR` or create
 `$XDG_DATA_HOME/RaptorReplica/mods/`. Saves and configuration use separate XDG
 `RaptorReplica` directories, with read-only legacy import.
