Blaze is a first person shooter action game using the DarkPlaces Engine. There may also be an extra model pack for some Doom engine(s) later. It is heavily inspired of Abuse, Doom and Quake series. The game environments will be sci-fi tech bases, alien hives, hell, etc.
This level has 3 portals into 3 other levels. Then you can play the levels in pretty much whatever order you want. You can also play them again. Player will also return back to the correct portal in the HUB level. The other levels could also have some connections, but not as much as the HUB levels.
Monsters and stuff will respawn going back to levels, but there could be some alternate monster layouts, which could change depending on player's status. The HUB levels could have some monsters too.
Note: it's not a final quality level.. as in the first HUB should have more than 3 portals... and wouldn't hurt to have some more details.
