Capybara

Capybara is a 22-level Boom-compatible (cl9)"speed slaughtermap" community project, consisting bizzare visual designs, unconventional combat designs and some challenging slaughtery gameplay. In this project everybody needs to finish making the maps within 24 hours and only have 4 days to work on them, note that this is not a strict rule. Majority of the maps are playtested with DSDA-Doom or Gzdoom, however note that you might suffer from unexpected lags in some grandiose slaughter situations. (a.k.a lots, lots of monsters)
