Born in 93, missed out on all the old school FPS games but this has given me a chance to play it and I do have a soft spot for Build. It's hard AS INTENDED It's rewarding SECRETS ARE ACTUALLY USEFUL It's rewards thinking DON'T SPAM TNT (You'll get yourself killed ;) ) It's a master piece! Environements, Enemy types, Bosses all feel well thought out and fleshed out even the user maps are exeplary in how to utilize the build engine due to more powerful PCs it allows for more creative liberties. Thanks Civvie 11!
